Above: Neurula with open neural plate and early neural ridges, C, Ct. Below the neural plate are the notochord, N, and the lateral mesoderm, M, Mv M and M1 are migrating ventrally. The endoderm, E, Ex extends dorsally. Right: A later neurula in which the neural ridges approximate each other. The notochord becomes segregated from the mesoderm. E and £x have met and fused, thus completing the'roof of the gut G. A is the archente
