Lesser Omentum - English Definition & Meaning

Definition

The lesser omentum is a smaller peritoneal fold that connects the lesser curvature of the stomach and the duodenum to the liver. Unlike the greater omentum, it's more delicate and primarily supports structures. Think of it as a connecting "bridge" between the stomach/duodenum and liver. It contains important blood vessels like the hepatic artery and the portal vein. It also contains the bile duct, transporting bile from the liver to the gallbladder and duodenum. The lesser omentum provides a pathway for these crucial vessels and ducts.

Etymology

The term "omentum" originates from Latin, meaning apron or covering. "Lesser" indicates its smaller size compared to the greater omentum. Its role involves suspending the stomach and duodenum from the liver. The term suggests a supporting structure. It reflects the omentum's specific function in connecting organs and transporting important vessels. "Lesser omentum" aptly describes this supportive peritoneal fold.
