great·er o·men·tum

[TA]
an areolar, four-layer peritoneal fold, formed by the double-layer dorsal mesentery of the stomach (dorsal mesogastrium) descending from the greater curvature of the stomach to fold under on itself and ascend to the transverse colon; the descending and ascending portions fuse, obliterating the inferior recess of the omental bursa, resulting in the four-layer structure that usually hangs over the anterior aspect of the intestines like an apron; components include the following peritoneal ligaments: gastrophrenic, gastrosplenic, splenorenal, and gastrocolic.
Synonym(s): omentum majus [TA], caul (2) , cowl, epiploon, gastrocolic omentum, pileus, velum (3)

greater omentum

n.
A fold of the peritoneum, passing from the stomach to the transverse colon. Also called caul.

greater omentum

Etymology: AS, great, large; L, omentum, entrails
a filmy, transparent double fold of the peritoneum, draping the transverse colon and coils of the small intestine. It is attached along the greater curvature of the stomach and the first part of the duodenum. It is a readily movable structure that spreads easily into areas of trauma, often sealing hernias and walling off infections that would otherwise cause general peritonitis, as can occur from a ruptured vermiform appendix. It also contains fat and keeps the intestines warm. Also called gastrocolic omentum. Compare lesser omentum.
