6 weeks of pregnancy. Development of the fetus

The term "6 weeks of pregnancy" is characterized by a number of important events in the development of the baby, in particular those related to the heart, the neural tube, as well as other organs and systems.

"Motor" crumbs are already beating, and several times faster than that of the mother. During the passage of the uzi at the 6th week of pregnancy, provided the quality apparatus and scanning, you can easily catch these very strokes. The heart is not yet fully developed, but very soon, namely at week 7, it will already be divided into the atria. No matter how surprising this may sound, the liver is still responsible for the reproduction of blood cells.

It is at 6 weeks of pregnancy that the neural tube is finally closed, by tightening the tissues. To ensure that at this stage there are no violations, it is mandatory to continue to take prescribed by the doctor folic acid. From the neural tube, or rather from its thickened part, the brain begins its formation. 6 weeks of pregnancy - this is the period in which gyruses and cavities begin to form. It is at this time that the baby's brain will take on a shape that is exactly the same as that of an adult! In addition, the cranium begins to form. Surprising is the fact that the muscles of the crumb and his heart are already starting to work under the control of the brain.

There is a constant division of nerve cells, which is why you should make every effort to ensure that the most important in the development of crumbs, the formation of the nervous system does not affect anything negatively.

The tail of the embryo lengthens and begins to disappear. Rapidly developing a 3-like intestinal tube, from which begins the formation of the respiratory, digestive and excretory systems. Very soon the upper part will turn into the pharynx and the larynx, the anterior part forms the esophagus, and the middle will become a thick and thin intestine, a secretory system will develop from the posterior part . Surprising is the fact that it is at 6 weeks of pregnancy there is differentiation on the basis of sex - the boy is an egg.

The development and laying of internal organs also continues: lungs, pancreas, stomach, liver. The formation of cartilaginous tissues begins, which will continue until the beginning of the third month of pregnancy. Bones, muscles and tendons are formed, the thorax develops.

The rudiments of widely planted ocular gaps, located on either side of the head, begin to approach each other. In comparison with other organs, they look huge at this stage. Also, the nose, mouth, jaws begin to loom, and the auricles on this term of pregnancy acquire a more complex form. On 6 week some rudiments of milk teeth are formed.

There are changes on the limbs, it is quite possible to see even the hands and feet, on which the little rudiments of fingers are drawn. For all this, the most striking is the fact that the fruit at this time is still tiny: its length is 4-8 mm. He is very small, but he was able to reach such a high level in his development!

6th week of pregnancy: sensations of mother

Feels like a woman at this time is not so beautiful as we would like. Toxicosis only increases, susceptibility to odors increases, and salivation and irritability may also increase. In the mammary glands, tingling sensations are felt, and the nasal areola darkens even more. It is necessary to try to treat all these changes positively, because all this is a normal reaction of a healthy organism to a properly developing pregnancy and a consequence of the results of the work of hormones. Although some women manage to live at this stage without much discomfort and anguish.
