The greater omentum is larger than the lesser omentum, which hangs down from the liver to the lesser curvature. The common anatomical term "epiploic" derives from "epiploon", from the Greek epipleein, meaning to float or sail on, since the greater omentum appears to float on the surface of the intestines. It is the first structure observed when ...

The lesser sac, also known as the omental bursa, is a part of the peritoneal cavity that is formed by the lesser and greater omentum. Usually found in mammals, it is connected with the greater sac via the omental foramen or Foramen of Winslow. In mammals, it is common for the lesser sac to contain considerable amounts of fat.
In human anatomy, the omental foramen (epiploic foramen, foramen of Winslow after the anatomist Jacob B. Winslow, or uncommonly aditus; Latin: Foramen epiploicum) is the passage of communication, or foramen, between the greater sac, and the lesser sac of the peritoneal cavity.
The greater sac, represented in red in the diagrams above. The lesser sac, represented in blue. The lesser sac is divided into two "omenta": The lesser omentum (or hepatogastric) is attached to the lesser curvature of the stomach and the liver. [5]
The peritoneal cavity is divided into the greater and lesser sacs. The greater sac comprises the majority of the peritoneal cavity, while the lesser sac, also known as the omental bursa, is smaller and situated posterior to the stomach and lesser omentum. They are connected by the omental foramen. [4]
At its commencement the greater curvature is covered by peritoneum continuous with that covering the front of the organ. The left part of the curvature gives attachment to the gastrosplenic ligament, while its anterior portion is attached to the two layers of the greater omentum, separated from each other by the gastroepiploic vessels.
Interposed between the hepatic and splenic flexures, the greater omentum adheres to the transverse colon along a further band or fold of peritoneum. Dissection through this allows access to the cephalad (top) surface of the transverse mesocolon. Focal adhesions frequently tether the greater omentum to the cephalad aspect of the transverse ...
