Rozvitok sq. Stages of embryo development day by day. Developmental period of the fetus: features

The intrauterine development of the fetus is a marvelous process. Over nine months of gestation, the embryo from one cell transforms into a functional organism ready for life. The development of an embryo is an incremental, natural process. The level of vacancy is determined by the size of the baby and the development of the singing organ system.

How does an embryo develop during pregnancy? Let's try to get back together.

Stages of embryo development

First to analyze the development of the embryo in the future, it is necessary to find out what the periods of intrauterine development of the fetus are.

After conception, a sperm cell with an egg is formed, a zygote is formed - a germ cell, which begins its journey from the woman’s fallopian tube in an empty uterus. After being embedded in the uterus, the fertilized egg attaches to the wall and the implantation process begins. After this, the baby's place is formed, this stage is called placentation.

All treatments are identical to what is observed in the embryo itself. The fertilized egg undergoes the first of two stages of development within an hour.

Stages of human embryo development:

1. The embryonic period is from the first to the eighth year of wine. This term refers to the active division and differentiation of all embryonic cells. The rudiments of all functional systems are formed. At the end of the embryonic period, the fetus looks like a human.
2. The fetal period lasts from the ninth year of winemaking to the time of birth. Malya begins to be called a fetus. There will be an increase in the size of your child, parts of the body, and functional systems will grow and begin to integrate into an independent life.

The following steps allow us to identify global changes in the human embryo. However, it is important to note that changes occur at every specific moment during the winemaking period.

First trimester of pregnancy

The intrauterine development of the fetus along the main stages of gestation is examined within the framework of the trimesters and skin month of pregnancy. There is no special sense in analyzing the development of the embryo over the course of a day, since during pregnancy, the meaning of changes is obtained for a rather trivial term.

From the moment of conception to the 12th stage of pregnancy, the first trimester proceeds - the hour of the most active and significant changes in the body of the human embryo.

From the first days, the division of the zygote into blastomeres - embryo cells begins, which during the first trimester transform into a full-fledged human organism.

How does this process work?

First obstetric month

Well, from the moment of conception the first obstetric month begins. In the middle of the fallopian tube begins a mass of oocytes filled with sperm. The baby's further development is expected in the following scenario:

• The first five days of development are occupied by the path until the uterus is empty. At the same time, the zygote actively divides and, as a result, transforms into a morula - a fertile egg, which reduces the number of undifferentiated cells.
• On the 7th day, egg implantation occurs.
• After this, the process of plantation begins. The arterial vessels of the organ join with the elements of the fetal membrane and form a special organ - the placenta, which ensures the safe life of the child.
• At this time, other extra-embryonic organs are formed - the umbilical cord, amniotic membranes.
• In the middle of the fruiting egg, the formation of organ embryos begins.

Another period of intrauterine development is no less significant. At this point, the placenta begins to actively form, and the umbilical cord is created. The baby's nervous system begins to develop, as nerve tubes begin to form - while still in its embryonic stage. This hour is a critical period of pregnancy.

Unfriendly officials of Dovkill can lead to the development of the nervous system.

Day 3 develop the knitting with significant changes in the middle of the fruit egg. This hour is set:

• Leaders of easy and savage paths.
• All organs of the herbal system.
• Judge the heart.

The nervous system is actively differentiated - the cob develops from the brain. And until the end of the third year, the baby’s heart begins to beat on its own.

What happens in the fourth year? The main changes are made by the following organs:

1. The rudiment of the intestine and liver is formed.
2. The differentiation of the vision system begins - the first rudiments of birth are present.
3. Legends are being confirmed.
4. The notochord is being established - this organ gives rise to most of the tissues of the ridge.
5. The differentiation of the neural tube will be completed.

Another obstetric month

5th day of the importance of connections with significant changes in internal organs. Among them you can see the following changes:

1. The molding of the liver is completed, and the baby's underside is laid.
2. The respiratory pathways from the larynx to the bronchi and leg are actively differentiated.
3. The growth of artefacts begins.
4. The eyes and inner ear are molded.
5. In the brain, different types differentiate among themselves.

Also change the shape of the ends and faces. There is already an empty nose and upper lip. The rudiments of nail plates are formed.

Sixth week of connection with progressive enlargement of the brain and ripening of the flesh. In addition, the rudiments of fingers become noticeable on the baby’s arms. Chambers are formed in the middle of the heart pulp. Sechoducts are formed from the rudiments of the organs of the thyroid system. And the intestines are divided into parts. The underside has been released and is ready to leave the robot.

The seventh period is special because the exchange of blood between mother and fetus is activated. Malya is actively collapsing. The functional development of the eye organ will be completed. The nasal and ear buds are visible.

With a stretch of 8 layers of wine, the body of the inner ear is painted. The human body system is actively changing - eggs are being formed in small human bodies. The appearance of a child begins to resemble the appearance of an adult person. The growth of the head and ends appears. The child’s fingers move towards the end of the look.

Third obstetric month

From this hour, obstetricians see the fetal period in the baby’s life, the baby’s body recognizes serious changes.

Main changes for the ninth year:

1. Accelerate blood flow through the arteries of the baby's space.
2. Development of the musculoskeletal apparatus.
3. The work of the heart is intense.
4. Formation of the cerebellum.
5. Development of supraneural glands and other organs of the endocrine system.
6. The cartilages of the larynx, ear, and vocal cords are formed.

The tenth day of knitting from the formation of reflex arcs in the nervous system. In addition, the most important part is formed - the diaphragm.

In the eleventh year, the iris of the eye develops, the organ of the eye is already ready to apologize. The placenta actively processes and ensures the essential delivery of metabolites to the baby’s body.

On the twelfth day, the internal organs significantly change:

• The intestinal vomiting increases and settles at the ventricular emptying in the form of loops. Peristalsis of the organ begins.
• The brain, despite its small size, already contains all the structures necessary for work.
• Leukocytes - cells of the immune system of the blood - begin to be produced.
• There are swellings of the chest cavity and diaphragms, which are predicted by the diaphragms.

Another trimester of pregnancy

As can be noted from what has been said, in the beginning of the next trimester the fetus is already greatly affected by the body of an adult. The main differences lie in the size and insufficiently high vulnerability of the rich organs. You yourself will change the baby’s recognizable body in another trimester.

Fourth obstetric month

Hour 13 is a long stretch of the moisture content of the knitting by changing the proportion of the baby. The size of the arms and legs increases, as well as the size of the chest. The head appears smaller compared to other parts of the body. The teeth aprons come in and the crown molding ends.

At the 14th degree, the facial part of the head changes. The forehead, nose, cheeks and chest begin to look like an adult. The skin on the baby's body is covered with small vellus hairs. The rocs will end in sirens. The differentiation of the thyroid system is reaching its end. The cutting is actively visible from the brunya. Insulin begins to be seen in the blood. Significant molding is involved in the state system.

Change on the fifteenth year:

• The walls of the arteries and veins thicken, the diameter and length increase.
• Antibodies are developed in the blood, and the blood type can be determined.
• The intestines begin to produce meconium - original feces.
• The development of fingers and toes will end.

At the sixteenth century, the baby’s body contains all its organs. The development of the skin and under skin continues. At an early stage of development, nail scarves are present. Ditini mush is formed.

Fifth obstetric month

The 17th day of the winemaking period is associated with the growth and development of the pelvic tissue, as well as the rudiments of milk teeth. The baby’s reaction to various sounds becomes noticeable, the baby begins to change its formation. From this period you can listen to the work of the heart.

The 18th day is significant because the baby’s sleep patterns and sleeplessness are taking shape. Many women begin to sense the ruins of a child.

In the nineteenth century, the ends become even stronger, all endocrine glands are actively working - from the pituitary gland to the thyroid gland. The blood contains monocytes and lymphocytes. The spleen begins to bleed blood.

The twentieth year is characterized by the following changes:

• Intensive development of cell tissue in every body.
• Development of the blink reflex.
• Expressions of mimetic hands.
• The coordination of the ranks is growing.

At this time, most women begin to feel the collapse of the fetus.

Sixth obstetric month

At 21 degrees, folds of the skin are formed behind the folds of the under skin. The baby is actively moving in the middle of the empty uterus. It’s better to sleep less and spend more than an hour in sleep mode.

22nd day of knitting from the completed formation of the ridge. The value of the brushes increases. Over the course of these days, the human brain actively develops. The heart is becoming more and more active in its work.

During the twenty-third year, it looks like this:

• Melanin, the pigment of the skin, vibrates.
• Most of the body is covered with ointment.
• The scrotum and ovaries are being formed.
• Wild roars are actively emerging.
• The intestines of a small person are intensively processed.

In the twenty-fourth year, the active growth of muscles and the well-functioning organs of vision and hearing are observed. An emotional bond is formed between the mother and the fetus.

Third trimester of gestation

The main purpose of the third trimester is the preparation of the body of the fetus before life in the womb. All organs will complete their development and their size will increase.

This itself will result in the influx of rich effects of dowkill onto the fetal body. The flock is protected by the use of many medicinal products. Today's mother pays great respect to her health.

Seventh obstetric month

The 25th day is characterized by the development of skin and adipose tissue. The baby's face clearly shows all the elements characteristic of an adult human. The cartilage swells with a thick consistency. The bones begin to soften and the cerebrospinal fluid begins to function. The alveoli are formed in the legs, the release of surfactant begins - the words do not fall off behind the shell of any leg.

At 26 years of age, the baby reaches a significant size, which is associated with the growth of meat and adipose tissue of the baby. In addition, continue to chew the brushes. It takes shape according to the sense of smell.

Change to 27 years:

• The work of the pituitary gland is active, as well as the thyroid gland.
• Individual mode of tissue and organ robotics, formation of speech exchange.
• Expressions of the fetal shaft in the middle of the empty uterus.

28th day of knitting from accumulated cellulose, changing the color of the skin. Continue to chew the cartilage and nails. One of the brains begins to dominate.

Eighth obstetric month

At 29 years of age, the amount of damage to the fetus changes. The mass and size of all internal organs grow. The organs of the sechovidlenny produce a great service of the seche.

30 days of tying with the development of the skin, as it develops a mature appearance. Legenes develop and the amount of surfactant increases. The number of connections between neurons increases as the number of connections between neurons increases.

At thirty, a child begins to sleep less and sleep no more. Malya is actively collapsing. The color of the iris is formed. The size and intensity of the work of the organs of the central nervous system is greatly increasing.

32 days of ties with the development of the leg, intensive work of the endocrine system. This is when the expectant mother's body begins the process of preparation for lactation.

Ninth obstetric month

The 33rd year is characterized by the development of the skin and an increase in the size of the nail plates. The hands of the fetus become more pronounced and grow richer. The position of the fetus becomes stable.

34th day of ties with offensive changes:

1. Increased myocardial mass - heart pulp.
2. The molding of the leg is completed.
3. The robot's brain will be strengthened.
4. The hair on your head takes on color.
5. A brush mass is formed.
6. The sections that are seen are becoming increasingly common.

On the 35th year there is no fear of changes. The organs continue to chew and prepare until the canopies.

At 36 years of age, the adipose tissue of the fetus becomes more and more differentiated and grows, the baby’s development no longer changes, the baby is getting ready for birth. All organs are completely at fault for living in the modern environment.

Tenth obstetric month

37th day of knitting with a development of adipose tissue. The baby's masa is growing a lot. The obligation of the most important speech to the surfactant reaches the necessary life position of the womb of significance. The scolio-intestinal tract contains strong peristaltic flows.

The 38th year is characterized by the progressive growth of children. The color of the skin resembles the color of an adult human.

At the 39th age, the baby takes the position in the middle of the woman’s pelvis, which is necessary for a flat position. The placenta has completed the process of metabolism.

At the age of forty, the little one is ready to live in the middle age. Changes in the mother are expected, which will lead to positive results.

Change in baby size

There are many changes in the size of a child during intrauterine development. This data is presented in the following table:

Remember that the size of the fetus and the size of its body are individual. The information provided never fails to influence the influence of external and internal factors on the body of mother and baby.

To ensure that your baby’s development is harmonious, try to minimize the influx of unpleasant factors and listen to your obstetrician-gynecologist.

Vagility is a wonderful time that conveys to a new man’s wife. For fathers, the skin of a child is unimportant, individual.

Wise nature has coined its own term for everything. Also, the development of the fetus in the mother’s belly is observed according to the laws.

Puberty is characterized by growth and developmental stages, from the formation of the embryo to the formation of the newborn pregnancy.

Knowing that the fruit is about to develop in the coming years, give the future fathers the joy and the love of marriage.

From conception to fourth year

The birth of life is a trivial process. Your period begins in the middle of your monthly female cycle.
On the fourteenth day of the menstrual cycle, the egg begins to mature and is transferred from the ovary to the fallopian tube. If the nearest object reaches out to the active spermatozoon and merges with it, then congestion will occur. Thus, a one-cell embryo, having matured, will become the germ of a new life.

Around the fourth day, the richly fertilized egg enters the empty uterus. Until the end of the third cycle, it is firmly attached to the walls of the uterus. Implantation, which has arrived, talk about conception. The villi of the outer cells of the embryo join with the blood vessels of the mother. This is the placenta. Other tissues will become the umbilical cord and membrane, which is related to the fetus. The internal tissues will soon be divided into 3 groups and become different organs and tissues.

From fifth to shost

Dear future mothers and fathers, the growth of the fetus and the baby in the future has been directed intellectually. The norm has not been established suvoro. There are no correct standards for the development of the fetus based on the level of gestation. Care on both sides individually.

“Vitaemo, you are flying!” - Previously, these words were often spoken by doctors, with the advent of express tests for vaginitis, they can be read in the instructions before the test. Most women call pregnancy and motherhood the most important time in life.

It is not for nothing that it seems that the woman’s attractive wife shines in the middle, she is especially beautiful and has become very attractive during this period. It's amazing, it's amazing! It’s a little bit of beatings, but, to be honest, if the mucus from the breast for 40 years of gestation results in a new life, otherwise you won’t get it

Vaginism is a physiological state of the body. These changes are programmed by mother nature. These table changes are so important that through them all women’s lives switch to a new rhythm: about 80% of women feel boredom, especially French women; the aroma intensifies, some of them smell unpleasant, leading to severe nausea and vomiting; the primary diet may change - if you love a hedgehog, you can click on the guide, and the food that was previously included in the list of hated ones may be listed in the first place; increased fatigue; annoying sleepiness; put some parts on sechovypuskannya; sudden changes in mood; tearfulness.

How vaginess begins and develops

Right in the middle of the menstrual cycle, one or more follicles mature in the ovaries. The follicle contains oocyte. The moment the egg leaves the follicle is called ovulation. After being released, the egg is picked up by the fallopian tubes and moves extensively towards the empty uterus. During this short period of time (3-6 days), the woman enters into direct contact without any difficulties, which is protected from pregnancy, which may arise. The egg cell vibrates special words that signal the sperm about where they are. As soon as the rendezvous arrives, there will be a delay. Vaginism begins.

The congestion occurs in the fallopian tubes, even before the release of the egg into the empty uterus. After the fertilization of the egg and sperm, the zygote is created, and the growth of the embryo begins.

What happens and what does the embryo look like? How does the size of the embryo change over the years? What changes are expected in the process of growth and development? How do photos of embryos look like? To monitor how the embryo develops over the past few months, ultrasonic scanning will be used.

Embryo 1st week

The zygote is still present in the uterine tube all the way to the uterus. The uterine tubes are lined with villi, which collapse the eggs at the side of the uterus. If the zygote does not reach the uterus within an hour, it can attach to the wall of the fallopian tube. In such a situation, talking about post-natal vaginity is not safe for one’s health and life.

At the hour of fertilization, the sperm bring in their 23 chromosomes, which combine with the 23 chromosomes in the egg. Moreover, due to the fact that the sperm has a place in its own X or Y chromosome, it must lie down to become a future child.

After fertilization and completion of zygote, it takes approximately 30 years. The fertilized egg begins to divide. This process is called crushing, because with a slight increase in the number of cells increases in geometric progression and their size changes. From 1, exit 2, from 2, exit 4, etc. With increased mass of cells, the gastrula transforms into a morula. The morula looks like a crowd of clumps of flowers. Until the 7th day after the enlargement, the morula transforms into a blastula. At the center of the embryo, an empty cavity is created, filled with liquid, or a blastocoel. The blastula disappears from the empty uterus and becomes enclosed in the mucus ball. This process is called implantation and involves the outer layer of the blastula, called the trophoblast. After cell implantation, trophoblast cells begin to produce chorionic gonadotropin, an important hormone that promotes vaginosis. Chorionic gonadotropin can be detected in the test, where its presence is determined by an additional rapid vaginosis test. Until the end of the first year, the size of the embryo is less than 0.3 mm.

Embryo 2nd year

At 8-9 days after the formation, the blastula transforms into a gastrula. In this case, the internal cells of the blastula are divided into 3 balls. The external sphere, or ectoderm, during the development process transforms into the nervous system and skin. The internal (endoderm) transforms into an empty scolio-intestinal tract. The mesoderm, the middle sphere, gives rise to the musculoskeletal system (brushes, ligaments and cartilages), meats, cervixes, blood vessels and internal organs. 10 days after the infection, you can cancel the positive result of the vaginosis test.

Embryo 3rd year

At the third stage, the embryo transforms into the neurula stage during the gastrula stage. The ectoderm at the sphere of the ridge creates a groove as it moves progressively deeper into the embryo. The edges of the groove are standing up. The nerve tube has closed, causing it to become the brain and spinal cord. The embryo that will become the baby’s heart is taking shape.

In the 3rd year, the placenta, the embryo’s life-support system, begins to form. The trophoblast and part of the ectoderm create the amnion and chorion. The amnion is popularly called the “shirt”. In the amniotic void, accumulated water is collected. Chorion is often created by villous tissue, which also produces chorionic gonadotropin. After an hour, the placenta is formed through the mesoderm and chorion. Until the end of the 3rd year, the embryo grows to a size of 4 mm.

Embryo 4 years

At the 4th deepest part of the nerve tube, the head and spinal cord begin to form. At the same time, my heart is breaking for the first time. Now don’t bother until the end of life.

The rudiments of arms, legs, eyes, and internal organs are formed. The blood vessels begin to leak blood. Until now, the embryo has been removed from the beetle sac, which, like in birds, contains the reserves necessary for the development of the embryo stage. In addition, the fatty sac in savants plays the role of the liver, cerebrospinal fluid, and liver. The honey sac itself contains new cells that migrate from there to the beginnings of the cells. After the appearance of the ovarian organs in the baby, the progression is known until the end of the first trimester.

Embryo 5 - 6 years

Embryo. 5 years from the moment of completion.

At 5 years of age, the umbilical cord is formed, as it binds the baby to the placenta. The umbilical cord contains arteries and veins. The length of the umbilical cord to the end of the canopies can reach 70 cm. The handles and legs are 5 cm similar to flippers, but it is also possible to separate the surrounding parts. The nervous system begins to generate first impulses - the basis of nervous activity. The head of the embryo is formed, it has openings for the ears, eyes, mouth and nose. The life of the embryo is 1 div.

Embryo. 6 years from the moment of completion.

On the 6th year it is already possible to separate the rice of the next individual. The ends and fingers are developing. Malya begins to feel the first signs. A pigment develops on the iris that represents the color of the eyes. At 6 years of age, the heart rate of the embryo can be examined with the help of an ultrasound scanner or ultrasound scanner. The placenta is completely formed. The rudiments of legen, nirok, statevih zaloz, schluka and intestine are formed. The embryo has already fertilized in the fertile water. The 6th day of pregnancy in the outer regions is considered the optimal time for the first visit to the gynecologist. It is necessary to perform an ultrasound scan, perform low-level tests, and undergo an examination by university specialists.

Embryo 7 years

At the 7th stage, the embryo develops a tail. The winter crevices are closing and overgrowing. Legends are beginning to take shape. Kintsivki will agree. External organs and lymphatic vessels develop. The cerebrum is growing. The heart is molded practically all the way around. Already marked on the tip of the nose and the forehead. The size of the embryo is 1.5 div.

Embryo 8 years

The nirks are starting to vibrate and cut. Hair follicles are being established on the skin. Perhaps all the important organs of life are already formed. Reflexions kick in, almost. Vushka pretends, revealing that she no longer looks like someone from a science fiction movie. It was amazing how tall the man was. The brushes are still formed from cartilage, so that the stench can leak out with calcium and transform into the old brush tissue. This whole process will be completed in less than 25 years, much later for the people. The size of the embryo is approximately 2 div.

Embryo 9 years

Now the little one can threaten with his fist, because there is something going on - his fingers can clench into a fist. The process of blood cell formation is transferred to the liver. The intestines flare up and settle in the stomach. You can clearly see the ear, eyelids, nose, mouth and eyes. The person is completely formed. The rudiments of teeth are formed. The baby is already 3 cm tall and very small in height.

Embryo 10 years

The baby's backsides are standing up. It is revealed in 28 years. The dichotomy system is practically completely molded. The skeleton appears to be completely human. The arms and legs will be restored to normal proportions. The head takes up almost half of the body. This is due to the active development of the brain and the growth of the brain. External state bodies are developing even after the sign of the state. You will soon find out how tall your stomach is. The baby's blood develops its Rh factor group. The growth can reach 7-8 cm.

Embryo 11 years

The little one is getting a comb-over. The fine hair on the head and body is called lanugo. At the moment the stench begins to disappear. The skin is open to the eye, blood vessels are visible. The first centers of ossification in the bones are being established. The blood contains white blood cells - leukocytes. The arms are pulled up to the point where the baby can put his finger near his mouth. The exercise begins to work - the baby can actively crumble in the womb, despite its size (10-15 cm) and small vagina (30 g) until the mother’s good health allows her to feel the collapse.

Embryo 12 years - 13 years

Embryo 12 years old. Photo

During this period, you can consult a doctor and perform ultrasound monitoring in the 3D reconstruction mode. Axis is the first portrait of your baby. Ultrasound is as close to 100% accurate as possible. At the hour of ultrasound, screening for developmental pathologies is carried out. You can now smear the finger - the smear reflex has appeared. The liver and the underside produce secretions. The intestines digest meconium - original feces. The formation of the article's organs is being completed. The baby's height is approximately 15 cm, weight 40-50 g. It doesn’t matter that the child is so small, but she’s already a human being. All organs are in their places, now your body will be resistant to negative influences. Become deprived of height. The first trimester has ended.

Embryo 14 years -15 years

Eyebrows will grow on your face. Now the face of the baby can express emotions - the expressions of expressions allow peaks, tears, and grimaces. Thick and long vines appear. Heartbreak can be achieved with a little help from an obstetric stethoscope.

Embryo 16 years -19 years

On the fingers Z'yavilovil Nigiki. My taste buds can sense the taste, and the receptors in my nose can detect the smell. Products that your mother gets used to may be suitable for you. The surface of the molded ear allows for a little sound. This includes my mother’s heart. The remaining research led to the original practical solution - for newborn children to play soft toys that promote maternal heartfelt. Respect that a calm heart will calm the child. Don't get nervous. The eyes begin to become bright.

And of course, during this period, mothers begin to recognize the thief in themselves. It is due to the negative connection with the mother. Malya may or may not sleep, depending on the period, as long as the thief is not detected. The baby's height is 20 cm and the weight is up to 250 g.

Embryo 20 years -30 years

Did you notice Stusan? Now the baby is so fond of his mother. Because mom is feeling sad, she’s probably embarrassed, because there’s so much loud music, it’s smoky, it’s stuffy, and the little one is bubbling out his thoughts. It’s awkward at first, but until the end of pregnancy, this method of sputtering is no longer possible. Constant pressure in the middle can be painful. The rapt noise and the mother's murmur are produced to a similar type in the child. Defense reflexes fade.

At the legs, the formation of the biliary alveoli is completed. The fingers become crooked on the hands. Naishvidshe go to develop the brain. Neural connections are being established. Malya can blink. The immune system is being established. The respiratory organs are sufficiently damaged to ensure the respiratory system at all times, except with medical assistance and special equipment. Adipose tissue is dissolved. Up to 30 years of age, height is 40-43 cm, weight up to 1.5 kg.

30 years – 38 years

The curtains are approaching. The child turns over with her head down, getting ready for the populace. Pushkova knows a hair behind his shoulders. In the legs, the fluid, which is called a surfactant, actively vibrates. It is necessary for preventing atmospheric winds, it protects the respiratory sacs and prevents them from sticking. Without surfactant, the skin may not open completely. In premature babies, this is the main reason that causes sore throat deficiency and death. At the time of birth, the baby's height is 52 cm, weight is about 3 kg.

The curtains begin in the middle at the 38th stage of conception, and doctors begin to define the term of vaginity in obstetric labors from the date of the beginning of the remaining menstruation. And here, 38 days of intrauterine development is comparable to 40 days of obstetric development. Embryology is the science that studies the development of the embryo and treats the child as an embryo from conception to maturity. 38 years old embryos develop in the mother. After 13 years, the embryo is already considered a fetus for the benefit of doctors. During the 13th century, the embryonic period transforms into fertile and fetal. This is related to legal aspects.

Bearing and giving birth to a child is an important test for any woman. However, the loss and joy of motherhood many times overwhelm whatever they feel. There will be sleepless nights and great restlessness in moments when the child is sick and worried. Kindergarten, school, adult life and child’s problems will always be at the forefront of your mind. Aje knitted you now the other way around.

We advise you not only to learn the facts, but also to take care of yourself, day by day, as the baby develops. The origins of life and vitality in the past with unique photographs taken by Swedish photographer Lennart Nilsson back in 1965. The photographer himself, born in 1922, became the first who, with the help of special equipment and cameras, was able to penetrate into the middle of a woman’s body and capture the entire process of the birth of a new life.

The first photographs of an embryo appeared in 1953, and this inspiration inspired the photographer to create new works.

In order to show the development of a person from the very beginning, by placing a micro-camera and a micro-illuminator at the end of the cystoscope tube, which examines the hair, and by taking your unique photographs directly from the stars to rob the first crumbs from the world. We know about the main aspects of pregnancy, the formation of a new life.

The sperm axis collapses in the face of the egg.

The sperm is pushed through the folds of the mucous membrane of the fallopian tubes in front of the egg.

Two sperm come into contact with the membrane of the egg. Enzymes, like those in the head of the spermatozoa, break down the membrane of the egg, and the genetic material of one spermatozoon takes its part in the fertilized one.

One of the 200 million father's spermatozoa, having broken through the membrane of the egg, literally pours into it.

Vaginism in a woman - 1 week

The beginning of a new life begins with a change in the female body, ovulation begins. This very moment is favorable for conception. It is possible for a woman to fertilize for only 3-4 days per month. Some women experience ovulation, others do not. Signs of ovulation may include increased vaginal mucus, increased basal temperature, and minor pain in the dilation of the ovary. Also, at the hour of ovulation, under the influx of hormones, a woman, as a rule, feels anxious about intimacy.

After a period of time, the embryo travels down the fallopian tube and moves into the uterus.

The fertilized egg begins to divide. With 46 father's chromosomes, the child declines 23, 2 of them - X and Y - flow into becoming the next child. When you give birth to a girl or a boy, the sperm will be deposited in the egg.

Over this period, the embryo moves along the fallopian tube and appears in the empty uterus. Near the end of the period, the veins attach to the wall of the uterus, growing into the mucous membrane. Sometimes implantation may cause minor bleeding.

Around this point, and sooner or later, a woman learns about her gravidity, knowing that her cycle is approximately 28 days. Daily menstruation. There may be signs of vagusness, such as fatigue, drowsiness, need for transportation, and increased sleepiness.

Vaginism in a woman - 5 years

The five-year-old embryo, the depth of 9 mm, can already be seen with openings for the mouth, nostrils and eyes. The central nervous system begins to develop, the spinal cord and brain begin to form. These processes lie in the presence of necessary substances in the mother’s body. I'm talking about folic acid - the most important element for the first trimester of pregnancy. Doctors recommend administering 400 mcg of folic acid daily to treat neural tube defects. Before the speech, even until the end of the fifth year, the child’s heart began to beat. Just now, more than anything else, the young mother is starting to think about the possibility of pregnancy and take a test and go to the doctor.

During the next trimester, if your waist rapidly expands, your breasts will become larger in the first trimester. This occurs independently of toxicosis. Blouses and sweaters become tighter, the bra is carefully tightened.

The fruit continues to grow and develop. The head cerebrum and ends are formed. The weight of the cruit's body is already the size of a whole gram, and the size is the size of a small grape. Malya begins to master the middle of life and crumble, but you still don’t understand it.

Since this age, the baby has proudly received the title “plid”. The most common problem of “the threat of pregnancy interruption in the early term” is long gone. Everything is fine with your baby, vaginity is developing as required, so the uterus does not hesitate to try to develop vagusity.

On ultrasound, you obviously won’t be able to tell who you’re counting on, a boy or a girl. External article marks are only beginning to take shape.

Vaginism in a teenager - 10 years

The instructions are already open. It will take several days for the stench to form on the surface. The baby is becoming more and more like a little person. This is one of the most important periods in a baby’s development, during the development of the nervous system and almost all organs. The placenta does not yet completely protect the baby from adverse factors, especially the effects of alcohol intake or other adverse factors that can cause severe problems both in the duration of pregnancy and in the development of the embryo in general.

Vaginality in a teenager - 11 years

In many cases, this term means that their ankles and feet have stopped freezing. The explanation is quite simple: the volume of blood increases and its circulation decreases, so hormones are infused into the thermoregulation of the body, which are released through vaginosis. At this very moment, the vagina increasingly begins to experience suffocation, weakness, frequent congestion and changes in arterial pressure.

Vaginality in a teenager - 12 years

This week marks the end of the first trimester. What life with your little one is going to be even richer. His blood already has red blood cells and white blood cells begin to vibrate - leukocytes, similar to the immune system of the body. So far, the stench cannot protect the baby from infection. A guarantee of your safety throughout intrauterine life and the first months after birth is passive immunity - antibodies that pass to the mother through the blood, and then through breast milk.

Vaginality in a teenager - 13 years

Well, that’s all, the first trimester was full of problems, toxicosis disappeared later. In front of you, the last golden hour is waiting for you, when you can enjoy your vagrancy. Your belly is already swelling with singing shapes, your pride in someone is growing, but at the same time it doesn’t matter to wear anything anymore, so with your great nakedness and great strength you can run around an entire children’s store.

Preparing the baby for the next trimester - development of the brush and growth. For which you need a lot of calcium, you should not forget about taking special complexes for your vagina. Apparently, before this term of agility is observed, the baby begins to perceive sounds using special vibration receptors located on the skin. This means that now you feel and, more than everything else, the sound of your voice is heard by that voice of the future dad. Your vocal cords are still being formed.

On the thirteenth day, the baby’s liver begins to vibrate, and the sub-sternal gland begins to produce insulin, and villi begin to form in the intestines, which play an important role in the over-poisoned hedgehog.

Vaginality in a teenager - 14 years

The baby has new needs. It’s time to “learn” about the wild hands - the stories and the sights, preparing to live like a womb. These training arms are very important for the development of legen fabric - for that very long-awaited first cry that the world has seen. The honeycomb and the honeycomb fur are formed, the nirkas begin to work, seeing the harvest. It will be absorbed by the accumulated waters and the placenta will be expelled.

The whole body of the baby gradually begins to cover the fluff, so-called lanugo, because it plays a hysterical function and helps regulate the body temperature of the baby. The small marks on the tips of the fingers - the ticks - are already marking a unique little thing that will be preserved throughout this life.

Men and women differ more from one another. In boys, the anterior ovary forms; in girls, the ovaries move to the pelvic area.

Neonatologists confirm that at about this hour the gestation begins to inform those who are working on it - they feel, and in their own way understand, that it is happening. You can express emotions using facial expressions and gestures. She senses mom’s mood, their sleep and wakefulness are synchronized.

The circulatory system is improved. The first hematopoiesis is brewing at the walls of the beetle powder. At 2-3 months of intrauterine development, the main hematopoietic organ is the liver, and at the end of the 3rd month - the cerebrospinal fluid. After 4 months, the spleen begins to suffer the same fate in the hematopoietic system.

Arteries and veins ensure the nutrition and supply of all organs and systems: the brain, heart, leg, vulva and intestines. In the fifteenth year of pregnancy, the baby’s heart beats twice as fast as its mother’s. Vono passes through itself up to 23 liters of blood per day. At any time, you can determine your blood type and Rh factor. You can be respectful if your mother is Rh- and your father is Rh+.

The child begins to coordinate her activities. The wine is actively collapsing - rolling around, overflowing and collapsing. Until all the thieves are sensed, the amniotic country will begin to soften the active hands of the uncontrollable.

Yogo denunciation is already well formed. At the sixteenth stage of pregnancy, the baby's eyes begin to blur.
The skin of the fruit is even thin, almost transparent. In photographs taken using additional ultrasound, it is clear that the subcutaneous fat ball is still completely visible - blood vessels are visible through the skin.

Your legs get more tired. Through an increase in body weight and a decrease in the center of gravity, the pressure on them increases. It appears to be a “rocking” motion, characteristic of carriages. You will have to endure high pick-ups and slippery soles.

The thirsty little one is already vikorist’s hands for vaccination around the area.

The skeleton of the larger one consists of a filamentous shear and lines of blood vessels, visible through the thin skin.

Vaginism in over 17 year olds

In the hour of urgency, you discover a lot of new things for yourself, not only in reality, but also in your dreams. Godly, the dreams of rich future mothers are bright. According to the Fahivtsev, this is due to overstrain, as your brain feels. In addition, you get up more often at night and therefore remember more dreams, but it becomes more difficult. In the seventeenth year of pregnancy, dreams are often associated with dreams or babies and can seem so real that they constantly spin in your head. Mothers often report nightmares - such dreams are filled with anxieties, as if they were stinking in the hour of sleeplessness.

Research shows that during the period of intrauterine sleep, babies also experience fluid movements in their eyes, while adults have such movements when dreaming. In connection with this, it has always been confirmed that babies can experience sleep associated with their activity and the passage of the day. Perhaps a child dreams of her stretching her legs, of hearing your voice playing with her umbilical cord.

Thief. The charmer will notice. In the seventeenth year of pregnancy, you are steadily picking up confirmation of what is in the middle.

Malya begins to serve the great and strong, so that her ruins will be similar to her future mother. At first you feel a vibration, then you feel like snowstorms are flying in your stomach, and then it becomes clear that there are signs of a baby. Throughout the year, a 5-month blanket can be produced in 20 to 60 pieces. Her strength varies depending on the time of delivery, depending on the mood and activity of the mother herself. Emotional outbursts, suffocating atmospheres, overexcitement, chocolate and malt - all this makes the baby collapse more actively.

If you still don’t sense a thief, there’s nothing terrible. Continue to listen to yourself and soon you will know the joys of the “first thief.”

Vaginism in people over 20 years of age

Mid-vagity. Equator.

You have already adapted to this rich condition and are increasingly thinking about future canopies. Haven't you picked up the courses of future fathers yet? It’s time to think about it. It is advisable to take up and train in such schools - it is good to prevent complications before the end of life and psychological problems after them. You receive information about the physiology of pregnancy and birth, about the peculiarities of monitoring newborns. You can discuss with your family members and other important diets that support your relationship with your child’s wines, relationships with relatives, and the treatment of the upcoming recession and recession.

Why are you being bullied by the thieves and psychology of intrauterine development? At the school you will find like-minded people and leaders who are ready to advise you on their nutrition.
If possible, try to combine activities with your next day.

Your little one is already close to 20 cm long. Hair is already starting to appear on his head.

Vaginality in adults - 24 years

If you put your ear to your stomach, you can almost feel the child’s heartbeat. The rhythm of a young person is more frequent; the lower one of an adult is 120–160 beats per beat. After the light appeared, the blood of the great and small stakes circulated. In the meantime, placental blood flow is of primary importance.

Blood, rich in the placenta with acidic and living substances, enters the body through the umbilical vein. The umbilical vein reaches the liver through the umbilical ring, and then to the inferior vein. Its arterial blood joins with venous blood, coming from the lower part of the body and the insides of the fetus. Most of the blood comes through the foramen ovale (the flow of blood from the right atrium to the left begins immediately after birth) at the junction of the right atrium to the left atrium. The left little hole leaks blood from a great deal of blood. The upper part of the fetal tube is provided with arterial blood more closely than the lower half of the body. This explains the clearly small size of the pelvis and lower ends of the newborn. There is very little blood left to be found.

Vaginality in a teenager - 26 years

At twenty-six, the little one is diligently exploring the vast expanse. There is still a place for active rulers. It is stitched, coated the umbilical cord and the walls of the uterus to seal it. Based on the Pearson test, which is recommended to be carried out over 28 days, the normal child should work about 10 days per year.

One of my favorite things to do in this regard is wetness of the thumb. This will relieve sore cheeks and cracks and will soothe you. The mucus reflex is one of the first insane reflexes, about oral segmental automatisms. It is formed during the first trimester of pregnancy and is preserved throughout the first stages of life. The advantage of the thumb of the right hand, or, incidentally, the left one may be a sign of dominance of the same or other brain. You can now guess whether the baby will be right-handed or left-handed.

Over the course of a month, the uterus increased in size by 4 times. Now it presses against the hypochondrium, bursting the lower ribs.

Vaginality in a teenager - 28 years

The lanugo (a thin layer of hair that covers the entire surface of the body, behind the lips, bottoms and soles) gradually knows that a few “islands” may be lost and after the curtains - on the back, on the shoulders and on the forehead. A stench arises from the first half of prenatal life.

The hair on your head becomes thicker. Some children, even among the people, can boast of thick, long curls, in others the head is practically a fox. Both those and others are variations of the norm. The visible absence of hair does not mean that there is no hair at all.

Whose life keeps opening and closing. They showed up. The nails on my feet are growing. Over the course of this period of vascularity, the mass of the brain gradually increases, and the number and depth of joints increases. These functions of measles develop even after birth. During the intrauterine period, the most important functions of fetal life are regulated by the spinal cord and other parts of the central nervous system.

There are still ten non-turbo days ahead, but the little man is already cramped in his mother, and is getting ready to leave. Turning your head down makes it easier to get out.

Vaginality in a teenager - 36 years

The future mother's body can begin active preparation for the baby's birth. There are signs of changes in the body that will occur shortly before the end of life.

• The nesting instinct is an internal need to prepare space for a baby to emerge;
• Change in height of the fundus of the uterus - or “dropping” of the abdomen;
• Removal of the mucus plug - removal of bark-free or erysipelas mucus from the cervix;
• Frequent discharge and defecation. The uterus, which has descended, presses harder on the sechovy mikhur and intestines. Prostaglandins that wilt during early pregnancy may periodically signal bowel movement;
• Change in the number of thieves. The child of the sky calms down and gains strength before the canopies of Mayday;
• Braxton-Higgs matches. Irregular, laborious things;
• minor changes in body mass;
• Softening and shortening of the cervix. It is possible to open the outer gap by 1-2 cm;

The weight of your baby is approximately 47 cm, and its weight is approximately 2600 grams.

After 4 years, turn it whiter. At this point, the plod is already nearing the end of the term.

During this period, from the fertilized egg, the organism develops, which contains the primitive parts of various systems and organs. Intrauterine development is divided into prenatal and fetal stages. The border between them is the end of another month of the life of the embryo, when it turns into a fetus.

Cob of cobs

Rosvitok fetus begins not during the embryonic period, but even earlier, even though the embryo develops from a fertilized egg, and the fertilized egg transmits the final development of state cells.

The pre-germination period includes the ripening of tissue cells and fermentation.

While in the ovaries of humans there is a constant renewal of cellular cells in an average of 2 months, then in the ovaries of women there is no constant renewal. After a girl’s birth, her ovaries contain approximately 400 thousand cells – the progenitor eggs that are given to her for the rest of her life. During the skin's menstrual cycle, one, sometimes two, eggs are released from the ovary. This process is called ovulation. After leaving the ovary, the egg cell is transported into the fallopian tube, where it becomes blocked - releasing female and human cells.

This will lead to the creation of a clearly new cell - the zygote. The zygote is inserted through the uterine tube into the empty uterus (this period lasts 7-8 days). When the zygote reaches the uterus, implantation begins - the implantation of the zygote at the wall of the uterus. The implantation process takes three days.

In the preparatory period, there is intense anatomical formation of the rudiments of organs that emerged during the illumination of the embryo, and new anlages appear: the Schulica and other parts of the grass tract are visible, the intestinal anlage of roses It is divided into sections, the division of muscles is formed, and the skeleton is formed. In the other half of the prenatal period, the facial parts are formed, the neck is formed, the circulatory system and organs are developed, the brain is formed, large grass buds are visible - the liver and the undergrowth. Until the end of the next month, the rudiments of all organs are formed and take their permanent place.

During the fruiting period, growth and functional maturation of the organs and tissues of the fetus occur. Beginning from this period, the organs of the fetus begin to function properly.

Another month. In the embryo (at the age of 4 - 5 mm), the tip buds become noticeable. Until the end of the next month, the embryo will increase from 5 mm (at the 5th week) to 25 - 30 mm. There are fingers and toes on the hands and feet that crumble; But these ruins are not yet felt by the mother. The long tail gradually turns into a small hump. The shiya is being formed. The cerebrum ceases to be visible through the skin. The rudiments of organs seem to be emerging from the protrusions and the cerebrum is sinking, during which the eyes may already be fully formed. The size of the head is very large (it becomes almost half the size of the whole embryo). The permanent apertures of the head structures of the individual are installed, as well as the ear shells, which are very low. The fetus’s body begins to function: the brain sends impulses to coordinate the functions of other organs, the heart beats, the Scholus sees the sac, the liver vibrates the blood cells. The rapid growth of the intestines, which began in the 6th-7th stage, leads to the point that some of the intestinal loops cease to fit into the small empty space of the embryo and extend beyond their boundaries. This is the name of the physiological umbilical hernia, which reaches full development by the end of the next month, and completely disappears by the 10th month. At the end of another month (8 days), the body of the fetus is formed, including the rudiments of the ends, on the head the rudiments of the eyes, nose, mouth, and the formation of the body organs begins.

Third month. The final dowzhina of the fetus, including the legs, becomes 7 cm, weight – 20 g. During the third month, the fruit grows rapidly and grows to the maximum. The head, as before, becomes noticeably large and by the end of the month becomes close to the dark-coccygeal age. The facial part is very small and aligned with the brain part of the skull. It is indicated that there is a growth of the hemorrhages, the edges of which grow among themselves at the 9-10th stage of embryonic development. The eyes open less frequently during the seventh month of pregnancy. The first hair buds appear (on the eyebrows, upper and lower lips, on the forehead). The ends are formed, the fingers and toes are visible, and the first points of ossification appear in the cartilaginous rudiment of the skeleton. The rudiments of nails appear on the fingers. The blanket is already grimacing. Special studies have revealed that fetal facial expressions stimulate change your face, my mother, I laugh and cry every hour. The table's hands rise so that the blanket can touch the head with your fingers, while clenching your fists. On the beginning of the third month, the sechostate and anal open. According to the structure of the external organs, it is already possible to determine the development of the fetus. Until the end of the third month, the skin begins to lose insight, which dominates the first two months of intrauterine life.

Fourth month. The total weight of the fetus, including the legs, becomes 15-18 cm, weight – 120 g. The head begins to grow slightly. There is vellus hair on the body. Hands and feet sway around the same time. The face is formed, the ossification of the skull begins, the formation of the meat system is about to complete, the ends of the stems become active, and the mother’s docks are compressed, the formation of the fetus becomes clear. The blanket crumbles a lot, you might wet your finger. The skins are covered with a bunch of balls. The functions of various systems of the body will be established. Using electron microscopy, it was established that the structure of the nerve cells in the brain of the fetal eye is almost the same as in newborns. It is already possible to hear the fetal heartbeat through the vernal wall of the vagina, the frequency of which is 120-150 beats per ear. Until the end of the fourth month, the abdominal swelling in the vagina becomes noticeable.

Fifth month.(Zagalna dovzhina of the fruit, including the legs, is 22 cm, masa – 300 g). The body is expected to grow more rapidly, and at the end of the fifth month of intrauterine development, the head will become a little larger than the body. The skin is a dark burgundy color. The subcutaneous fat ball begins to dissipate. The skin is covered with vellus hairs. Sebaceous follicles begin to see a fatty lining, which joins the epidermis and creates a syrupy paste. This oil protects the fetus from the steady influx of accumulated waters, and then makes it easier to pass through the ancestral paths. Meconium settles in the intestines. It is important to tighten the lower ends. The fetus can be born alive, there will be wild roars, but for such a term of virility we call it undead.

It is not so easy for the nacoploid fur as roach activity increases. On the 3rd and fifth month, the woman, pregnant first, begins to feel crumbs. The dates are re-marked 10 days earlier. The kidneys are even weaker - women can lose them due to intestinal shortcomings. Later effects on the fetus become more and more intense, and they can no longer be confused with anything. The first registration of the mother's hands of the fetus is an important sign that allows us to calculate the date of birth.

Sixth month. The total weight of the fruit, including the legs, is 30 cm, weight - 800 g. The skin of the fruit should be wrinkled, perhaps due to the lack of speed of growth of the fruit itself and its skin skin. Your eyebrows will become darker. On the pads of the fingers, scallops appear. Our little one is unique and unrepeatable. At this hour, the development of measles cells in the brain is basically completed. This waste will not be replenished under the influx of any damaging factors. Throughout life, people live with this number of cells that formed the cerebral cortex at that time. The fruits of the child become differentiated. Monitoring the fetus with the help of ultrasound tracking, the Germans began to use the hands to determine whether the fetus is in the state of sleep or sleep. The organ systems of the fetus continue to develop, learn new functions, but are not yet fully developed and do not adequately support the life of the fetus in the womb.

Seventh and eighth month. The full length of the fetus, including the legs, becomes 35-40 cm, weight - 1200-1700 g. The underbelly fat ball increases, and the skin becomes thicker and smoother. In this month of pregnancy, the fetus's eyelids open. Vine knows how to flatten and flatten eyes. At that time, his entire body is covered with downy downy hairs. In the rest of the year, the increase in energy goes mainly to the subcutaneous adipose tissue, which ensures a stable body temperature after the sun goes down. All the most important systems of the body are subject to fault and can, even if by force, with special attention, support the vitality of the uncontrollable position of the mother’s body.

You can be born and live until about seven and a half months. Children who are born during the third trimester (from this month until the end of pregnancy) are expected to live longer, if they want to be closer to the term assigned to them, and have a chance to survive, and ease of development. New sleep will significantly increase. Until the end of pregnancy, antibodies from the mother penetrate through the placenta to the fetus, creating short-term resistance to illnesses to which you have immunity. Premature babies experience less pain, but lower term babies are more susceptible to infection.

Ninth month. The final length of the fetus, including the legs, becomes 45 cm. Due to the strong deposit of fat in the adipose tissue, the shape of its body becomes more rounded. The nails on the hands reach the tips of the fingers. The hair on the head becomes thicker and longer. The plaid, which was born in this term, is life-giving, screams loudly, flattens the eyes, expresses the mucus reflex.

In the eighth – tenth month the rate of fetal growth decreases. The wine is already so great that it is cramped in the thick fur. In this situation, the best position, which will ensure maximum looseness in a mild mother, is with her head down. A plaid that develops normally receives it. The smut is most amenable to canopy support. Until the end of the ninth month, the fetal body is thoroughly prepared for prenatal life. The lower hairs are lost on the front of the shoulder. Its expression and width throughout the body may indicate a lack of fetal maturity.

Tenth month. The birth date of the fetus, including the legs, is 50 cm, weight – 3000 g. Until the end of the tenth month of pregnancy (38-40 years), signs of prematurity appear, and pregnancy becomes evident. It is rare to be aware of inconsistencies between the term and maturity of the fetus. Due to unsympathetic development (mother's illness, insufficient or improper nutrition, etc.), the child is born to term and may show signs of immaturity. Sometimes you have to beware of the worst case: the child is born a few years earlier than the term, before we mature.

In the rest of the month, there will be more growth in the lower ends, and the difference between the two and the upper ends is smoothed out. However, only after the birth of the people, their feet melt into hands.
