Fetal brain development
Once a woman conceives a pregnancy, a new life starts. In the first eight weeks, it is just called embryo, while from that week to the end of the pregnancy, it is called fetus. The development of the brain in the fetus includes the development of the brain together with the nervous system and the spinal cord. Fetal brain development timeline
In the first two weeks of pregnancy, the fertilized egg is implanting inside of the uterus. In the third week the heart, the backbone and the brain of the embryo start to form. The further development of the brain continues in the fourth week of the pregnancy when fore, middle and hindbrain begin to be distinguished together with the optical stalk. In the fifth week, the brain continues to develop while the heart with the four chambers formed starts to function. During this week, the embryo gets facial features, as well as arms and legs with the fingers. The brain hemispheres are formed in the sixth week of the pregnancy.
