Term Detail
MP term:abnormal visceral yolk sac morphology
Synonym: abnormal secondary yolk sac morphology
Synonym: abnormal umbilical vesicle morphology
Synonym: abnormal vitelline sac morphology
Synonym: abnormal yolk sac morphology
MP id: MP:0001718
Definition: any structural anomaly of the extraembryonic tissue membrane, formed from the visceral endoderm and the extraembryonic mesoderm, which is located ventral to the embryonic disc and is connected to the presumptive midgut of the embryo; the yolk that it contains is the site of embryonic hematopoiesis and vitelline circulation is involved in early embryonic circulation; it is the origin of the primordial germ cells
