The shape of the root of a completely formed spinal nerve, as it appears in an embryo of the fourth day, is represented in Fig. 68. The Eye. In the preceding chapter we saw how the first cerebral vesicle, by means of lateral outgrowths followed by constrictions, gave rise to the optic vesicles. These and the parts surrounding them undergo on the third day changes which result in the formation of the At their first appearance the optic vesicles stand out at nearly right angles to the long axis of the embryo (Fig. 27), and the stalks which connect them.
