Fig. 75. Showing the growth backwards of the Somatopleuric Head Fold in the human ovum of 15 days to form the Amnion and Prechorion

The condition of the membranes in the 3rd month (Fig. 76) differs from that of the 1st month (Fig. 75) by the formation of the placenta. In the first month the chorion is uniformly covered by shaggy villi, which project into the decidua and draw sustenance for the embryo therefrom.
