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.

Generally, these include the following stages: (I) Chemoattraction of sperm along a chemical gradient to the egg; (2) movement of the sperm through the egg jelly coat and initial attachment of the sperm to the vitelline envelope; (3) induction of the acrosome reaction, resulting in the release of acrosome proteins and the opening of a hole in the vitelline envelope layer (either enzymatically or non-enzymatically); (4) the movement of the sperm through the previtelline space; and (5) the fusion of the sperm membrane with the egg membrane (Fig.
