A double fold of peritoneum attached to the stomach and connecting it with certain of the abdominal viscera. It contains a cavity, the omental bursa (lesser peritoneal cavity). See: illustration

gastrocolic omentum

Greater omentum.

gastrohepatic omentum

Lesser omentum.

greater omentum

The portion of the omentum that is suspended from the greater curvature of the stomach and covers the intestines like an apron. It is the largest of the folds of the peritoneum. It dips in among the folds of the intestines and is attached to the transverse colon and mesocolon. It contains fat, prevents friction, and aids in localizing infections.
Synonym: gastrocolic omentum

lesser omentum

The portion of the omentum that passes from the lesser curvature of the stomach to the transverse fissure of the liver.
