Celiac artery Preventative health Biology Diagrams What are the greater omentum and lesser omentum? Learn about the anatomy of these divisions of peritoneum at Kenhub!
The omentum pass from the stomach and the first part of the duodenum to other abdominal organs. The size of the omentum varies from 300 gm to 2000 gm with a surface area of 300 cm 2 to 1500 cm 2 1. There are two omentum: Greater omentum, derived from the dorsal mesentery, and Lesser omentum, derived from the ventral mesentery. The greater sac comprises the majority of the peritoneal cavity. The lesser sac (also known as the omental bursa) is smaller and lies posterior to the stomach and lesser omentum.

The Peritoneal Cavity Biology Diagrams
Greater and lesser omentum The greater omentum is the larger of the two peritoneal folds. It consists of a double sheet of peritoneum, folded on itself so that it has four layers. [2] The two layers of the greater omentum descend from the greater curvature of the stomach and the beginning of the duodenum. [2] They pass in front of the small intestines, sometimes as low as the pelvis, before

The lesser omentum is a double-layered peritoneal fold that connects the lesser curvature of the stomach and the proximal part of the duodenum to the liver. Posterior to the lesser omentum, there's a space known as the lesser sac or omental bursa, and the rest of the peritoneal cavity is known as the greater sac.

In this tutorial video I am explaining the anatomy of the greater omentum and lesser omentum.Parts of the greater omentum: - Gastrophrenic ligament - Gastros The omentum is a double-layered extension of the peritoneum that connects the stomach to adjacent organs. The peritoneal reflections form the greater and lesser omenta, and the natural flow of peritoneal fluid determines the route of spread of intraperitoneal fluid and consequently of disease processes within the abdominal cavity.
The greater omentum is a significant and complex structure within the abdominal cavity, known for its large, apron-like appearance. It hangs from the greater curvature of the stomach and extends down to cover the small intestines before folding back upon itself to ascend to the transverse colon, connecting eventually to the posterior abdominal wall.
