Preferred Label : yolk sac;
MeSH definition : The first of four extra-embryonic membranes to form during EMBRYOGENESIS. In REPTILES
and BIRDS, it arises from endoderm and mesoderm to incorporate the EGG YOLK into the
DIGESTIVE TRACT for nourishing the embryo. In placental MAMMALS, its nutritional function
is vestigial; however, it is the source of INTESTINAL MUCOSA; BLOOD CELLS; and GERM
CELLS. It is sometimes called the vitelline sac, which should not be confused with
the VITELLINE MEMBRANE of the egg.;
MeSH synonym : embryo vitelline sac; sac, yolk; sacs, yolk; embryo vitelline sacs; vitelline sac of embryo; yolk sacs;
