Content: In this period the neural tube, which links the spinal cord and the brain, is also formed. Until the end of the seventh week of the pregnancy, the brain formation is almost completely finished. The eighth week of the pregnancy is characteristic for the big head, as well as for the hindbrain development, which controls the heart rate and breathing. While in the ninth week, the nervous system is almost completed for its proper functioning, and in the tenth week, the fetus develops the genitals so that the sex of the baby can be seen through the ultrasound. In the tenth week, the brain starts to form even 250 000 neurons in a minute. In the eleventh week, the spinal cord is defined, while vocal cords and taste buds are formed in the twelfth week. The week thirteen is characterized by the complete forming of the heart, the spleen and the liver, while the fetus begins to use placenta to take nourishment from the mother in the fourteenth week. The hair grows on the skin in the fifteenth week, while in the sixteenth week the mother can feel the kicking of the baby. Throughout the seventeenth, eighteenth and nineteenth week of the pregnancy, the fetus develops the brain very rapidly and the brain is now divided into the left and right brain hemispheres. From the twentieth to the twenty-second week the brain furthers develop and now it is possible to recognize different sounds.
