    • n Omentum (Anat) A free fold of the peritoneum, or one serving to connect viscera, support blood vessels, etc.; an epiploön.☞ The great, or gastrocolic omentum forms, in most mammals, a great sac, which is attached to the stomach and transverse colon, is loaded with fat, and covers more or less of the intestines; the caul. The lesser, or gastrohepatic omentum connects the stomach and liver and contains the hepatic vessels. The gastrosplenic omentum, or ligament, connects the stomach and spleen.

    • n omentum In anatomy, a fold or duplication of peritoneum, of two or four peritoneal layers, passing between or hanging down from certain abdominal viscera—the stomach, liver, spleen, and colon. An omentum is a structure similar to a mesentery, and is in fact a special mesentery connecting the stomach with the liver, spleen, and colon respectively. Hence omenta are commonly distinguished by name. The gastrohepatic or lesser omentum, omentum minus, is a single fold (two layers) of peritoneum extending between the transverse fissure of the liver and the lesser curvature of the stomach. Between the two layers are the hepatic artery, portal vein, bile-duct, and associate structures, bound together in a quantity of loose connective tissue forming Glisson's capsule. The gastrosplenic omentum, of two layers, connects the concavity of the spleen with the fundus of the stomach, and contains the splenic vessels. The gastrocolic or great omentum, omentum majus, also called epiploön, is the largest of all the peritoneal duplications, and consists of four layers of peritoneum attached to the greater curvature of the stomach and to the transverse colon, whence it is looped down freely upon the intestines, forming a great flap or apron.
