At the 7th obstetric week of pregnancy, the body size of the embryo is less than 1 cm. Great changes are taking place in this tiny little body. Active growth of the brain leads to a rapid increase in the size of the head and its isolation on a relatively small body. In the same period, in the upper part of the brain tube, there are 5 brain bubbles, from which all the main sections of the brain will be formed.
For a period of 7 weeks, the differentiation of the main structures of the face continues. An outer ear arises at a proper place, a nose, jaws and lips are formed. Eyes appear, thin cilia are formed, a retina is formed. There is a laying of the optic nerve and the formation of connections between the organ of sight and the brain.
