Greater Omentum & Lesser Omentum
Lesser and Greater Omenta
- The lesser omentum extends between the liver and the stomach and duodenum; can be subdivided according to its specific attachments:
- The hepatogastric ligament connects the liver and the stomach.
- The hepatoduodenal ligament connects the liver and the duodenum.
- The greater omentum is a single fold of peritoneum that comprises two double-layered sheets of peritoneum.
- More specifically, it arises anteriorly from the greater curvature of the stomach, and posteriorly from the abdominal wall above the small intestine; thus, as it grows, it drapes over the transverse colon and small intestine.
