vitelline diverticulum
small outgrowth from the avian jejunum marking the previous connection to the yolk sac. See also meckel's diverticulum.
persistent vitelline artery
creates an anomaly, a mesodiverticular band, stretching from the cranial mesenteric artery to the site of a Meckel's diverticulum, that may entrap a loop of intestine and cause its strangulation.
persistent vitelline duct
creates an anomalous fibrous attachment between the site of a Meckel's diverticulum and the umbilicus. A partial band, reaching only part way to the intestine, may also be formed. Either development may result in an intestinal strangulation.
vitelline membrane
the external envelope of the ovum.
vitelline vessel
omphalomesenteric arteries and veins through which blood passes to and from the primitive heart, and the yolk sac and midgut of the embryo.
