Neural Groove

A series of transverse sections through an embryo of the dog. (After Bonnet.)

The series shows the uprising of the neural folds to form the neural canal.

Section I is the most anterior. In V the neural plate is spread out nearly flat.

Section III, IV, and V the scattered cells represented between the entoderm and splanchnic layer of mesoderm are the vasoformative cells which give origin in front, according to Bonnet, to the heart tubes, h; l.p.

Lateral plate still undivided in I, II, and III; in IV and V split into somatic (sm) and splanchnic (sp) layers of mesoderm.
