Anatomical terminology []

The connecting stalk is a yolk sac diverticulum.

It is derived from extraembryonic mesoderm.

Progressive expansion of the amnion from the umbilical ring (surrounding the roots of the vitelline duct and connecting stalk) creates a tube of amniotic membrane. The amniotic membrane and its contents form the Umbilical cord (Larsen's Embryology, 5th edition, p138).
