Fetal development in the 27th week of pregnancy

Every day the baby’s prenatal life is a truly unique event. This article will tell about the features of the development of the child at week 27.

To determine how fully a baby grows, doctors use special ultrasound examination methods. When conducting such a study, the doctor can get the main dimensions of the actively growing child.

The normal values ​​of the determined parameters at each time interval of pregnancy differ. The table that follows shows norms of the main clinical parameters of the fetal body, determined during fetometry.

In addition to determining how much a baby weighs and how long it is, with the help of the same ultrasound examination, specialists can see how the fetus looks. Modern devices, on which such types of research are carried out, make it possible to obtain a fairly clear picture with the main features of the child’s face in the womb.

The main features of the crumbs by the 27th week are already quite well formed. The ears are small and start to move slightly to the sides. Eyeballs outside cover the eyelids.

Above the upper edges of the eyes of a child grow small eyebrows. The fetus has even formed small lashes. With each subsequent day of pregnancy, the child becomes more cute. His skin gradually acquires physiological color and becomes pale pink with a gray tint due to the original lubricant.

On the body of the child - many wrinkles. They appear mainly due to the fact that the fruit is always in the aquatic environment. The impact of amniotic fluid contributes to the fact that the skin becomes wrinkled.

Baby by the end of the second trimester of pregnancy is already becoming more plump. The change in its appearance is due to the fact that under the skin of the fetus the amount of brown fat begins to actively increase. It is necessary so that after his birth the child simply does not overcool. Brown fat appears in the children's body is not accidental - it is able to quickly enter into the metabolism and, if necessary, to give the child energy. That is why there is a lot of brown fatty tissue in the children's body.

The cheeks of a child every day are becoming more prominent. This feature is also largely due to the accumulation of brown fat in the children's body. The baby has characteristic dimples near the elbow pits, as well as the first fat folds on the body.

Fetal development of the fetus to this period of pregnancy undergoes a number of features.The main vital internal organs of the baby have already been formed, many of them even begin to function. To carry out work in full-fledged mode, the internal organs will be able only after the birth of the child. In the meantime, this mode of their work can be called "training."

By the 26-27th week of gestation, the secretory organs show their efficiency in the child. Thus, the concentration of certain hormones increases in the baby’s blood. Scientists have found that the fetus already has its own somatotropin, thyroxin, insulin and other important hormones. The pituitary, thyroid, and pancreas are involved in their formation.

By the 27th week of pregnancy, the child’s nervous system is already functioning quite well. A characteristic feature of this period is the active development of certain parts of the brain responsible for thinking and mental activity. Scientists have found that the total number of furrows and convolutions that give the cortex a specific striation continues to increase daily until the onset of labor.

Such a special structure of the "main computer" in the children's body contributes to the fact that every day the fetus increases the number of reflexes that it needs for later life.

Intensive development of the organs responsible for the perception of various environmental stimuli, contributes to the fact that the child begins to change the sensations he experiences. By the 27th week of its intrauterine life, the crumb is able to experience quite a lot of different emotions.

The perception of various sounds is a rather vivid sensation that a fetus is capable of experiencing in this period. A child can quite easily distinguish between parental voices. His mother’s voice has a special positive effect on him - It is proved that the mother's voice has a relaxing effect on the baby.

With each successive day of pregnancy, the number of sounds perceived by the baby increases. In addition to the voices of his parents, the baby is able to perceive sounds from the external environment. Baby can already hear the sound of the TV or radio. Of course, he cannot yet make out the speech and the meaning.

The fruit distinguishes sounds mainly in intensity and volume. So, excessively loud sounds can cause a certain discomfort for the baby. In this case, the child’s mood change will quickly be felt and his mother, the baby, will begin to kick and move strongly.

An excellent option for spending time on this gestational age is reading baby tales or listening to music. There is an opinion that the formation of musical taste in a person occurs exactly in the second trimester of pregnancy, therefore it is possible to consciously form musical preferences in a child. To do this, listening to the classics is best suited - it definitely will not cause a negative for the baby.

At week 27, the baby is able to open and close his eyes. During the period when the child is awake, his eyes are ajar. Light falling on the face of the baby, is able to cause him a response. For example, scientists conducted a series of scientific studies proving that a bright light falling on the face of a fetus leads to the fact that it tries to turn its back on the rays in every possible way.

Doctors believe that the child’s visual analyzer will truly function only after birth. Long and very strong insolation contributes to the fact that the motor activity of the fetus increases.

Before the onset of labor a few more weeks, and the baby can already distinguish between tastes.Special microscopic outgrowths on the tongue help it in this. They are a kind of receptors that are responsible for the perception in the human body of various taste options.

Recognizes the taste of the amniotic fluid of the baby when swallowed. During the day, he is able to swallow about 500-600 milliliters of liquid. Amniotic fluid passes through the baby's digestive tract inside, where some nutrients are absorbed. The most important substance that gets into the bloodstream in this way is glucose. Without it, it is impossible to fully develop the nervous system, in particular, the brain.

The baby, which in its size resembles an average cauliflower head, is already able to distinguish between a bitter, salty and sweet taste. Swallowing a fairly large amount of amniotic fluid causes the fetus to hiccup. This manifestation of the life of the baby is quite normal and indicates the gradual development of the digestive system.

One of the brightest characteristic signs of the 27th week is quite intense physical activity of the fetus. The active movements of the child at this time are already able to be felt by his mother, and many women note that at the 27th week of pregnancy, the physical activity of their babies was quite pronounced. Such a vivid sensation, which feels a pregnant woman in her stomach, contributes to the rather large size of the fetus.

The number of movements performed by the fetus increases significantly. The child is already bored with studying his own body by the 27th week of intrauterine life; now he is more interested in the aquatic environment in which he is. Every day it becomes interesting for a child to explore the boundaries of the world, where he still “lives”.

This research interest leads to the fact that the child can push the uterus wall with its legs. Such a tremors in his stomach and feels a pregnant woman. Also curious fidget can touch the walls of the uterus with his own hands. Shocks and movements in a pregnant woman can occur in different parts of her stomach, this is affected by the position of the baby in the uterus.

It is important to note that not all the time during the day the fetus is active. The baby already has a circadian rhythm, that is, the ability to recognize day and night. In the daytime, the child is usually quite active, whereas at night he sleeps. The sleep of the fetus at this stage of its intrauterine development lasts, as a rule, at least 16-17 hours a day. Some babies can sleep longer - up to 20 hours.

Every day the weight of the child increases - this is necessary so that the baby can soon be born. In order for a child to gain weight well, it is necessary that all the necessary nutritional components, as well as oxygen, are regularly supplied to his body. Without the full work of the heart is impossible.

By week 27, the baby’s cardiovascular system is not only formed, but is functioning. Thanks to the “pumping” function of the heart, all nutrients that come through the uteroplacental circulatory system are delivered to their destination - to all internal organs.

It is possible to clinically evaluate the work of the heart by applying a fairly simple diagnostic method — counting the heart rate of the fetus. Each segment of pregnancy is characterized by certain normal rates of fetal heart rate (HR).

The position of the crumbs can be different, and the most favorable location is called head presentation. In this case, the risk of various adverse injuries and damages during delivery both to the mother and the fetus is minimal. Natural childbirth in this case is quite possible.

A less favorable option is pelvic presentation, in which case caesarean section is the preferred method of obstetrics.

The transverse position of the fetus in the uterus is also one of the unfavorable options. In this case, the baby lies as if perpendicular to the axis of the uterus, the main parts of his body are located above the iliac crest. If the position of the baby does not change before the birth, then, most likely, doctors will also resort to a cesarean section.
