Omentum

The apron of fatty tissue that hangs down from the stomach to cover most of the front surface of the abdominal region.

A double fold of peritoneum hanging down over the intestines.

Omenta, fold of peritoneal tissue attaching and supporting the stomach and adjacent organs.

A double fold of the membrane lining the abdominal cavity. The greater omentum attaches to the stomach and hangs down over structures close to it, including the duodenum and colon. The lesser omentum covers the liver and parts of the stomach and small intestine. These folds store fat and may also prevent the spread of infection between abdominal organs.

A double layer of peritoneum attached to the stomach and linking it with other abdominal organs, such as the liver, spleen, and intestine. The greater omentum is a highly folded portion of the omentum, rich in fatty tissue, that covers the intestines in an apronlike fashion. It acts as a heat insulator and prevents friction between abdominal organs.

A long fold of peritoneal membrane, loaded with fat, which hangs down within the cavity of the abdomen in front of the bowels. It is formed by the layers of peritoneum that cover the front and back surfaces of the stomach and extend from the lower margin of this organ to cover the back and front surfaces of the large intestine. Instead of passing straight from one organ to the other, these layers dip down and form a fourfold apron. This omentum is known as the greater omentum, to distinguish it from two smaller peritoneal folds, one of which passes betweeh the liver and stomach (the hepatogastric omentum), and the other between the liver and duodenum (the hepato-duodenal omentum). Together these are known as the lesser omentum.

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).

The peritoneum is a layer of tissue that envelops the abdominal organs. Its name is derived from the Latin word for “apron,” reflecting its apron-like structure and function.

A folded layer of fatty membrane within the abdomen (peritoneum) that hangs in front of the intestines, functioning as a storage site for fat.
