Text-fig 7. Schemes of the chief stages in the development of the human embryo

In stage 7 (text-fig. 7, corresponding approximately with the embryo Bi II) the axis of the stalk lies still more caudally, being now situated behind the allanto-enteric diverticulum. The cloacal membrane is divided into two parts: one of them lies at the orifice of the diverticulum, the other is situated more caudally.

Ectoderm black; entoderm lined horizontally, primitive streak vertically, head process and chorda plate obliquely. Mesoderm dotted. The axis of the connecting stalk is marked by an arrow. The limits of the connecting stalk are marked by * and ʘ, the limits of the umbilical stalk by + and ʘ). The direction of the extension of the amniotic cavity towards the connecting stalk is marked by arrows. The parts of the allantois and of the axis of the connecting stalk situated out of the median plane are finely dotted. A. Connecting stalk; B. umbilical stalk; Cl.m. cloacal membrane.
