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]
The lesser omentum (small omentum or gastrohepatic omentum) is the double layer of peritoneum that extends from the liver to the lesser curvature of the stomach, and to the first part of the duodenum. The lesser omentum is usually divided into these two connecting parts: the hepatogastric ligament, and the hepatoduodenal ligament. [1]
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.
The omentum are specialized folds of peritoneum that enclose nerves, blood vessels, lymph channels, fatty tissue, and connective tissue. There are two omenta. First, is the greater omentum that hangs off of the transverse colon and greater curvature of the stomach. The other is the lesser omentum that extends between the stomach and the liver. [1]
In human anatomy, omentum (Latin for ' apron ') refers to a fold of the peritoneum, a thin membrane lining the abdominal cavity and the abdominal organs. The term may refer to two structures: The term may refer to two structures:
The mesothelium is composed of an extensive monolayer of specialized cells (mesothelial cells) that line the body's serous cavities and internal organs. The main purpose of these cells is to produce a lubricating fluid that is released between layers, [ 4 ] providing a slippery, non-adhesive, and protective surface to facilitate intracoelomic ...
anterior: the free border of the lesser omentum, known as the hepatoduodenal ligament. This has two layers and within these layers are the common bile duct, hepatic artery, and hepatic portal vein. posterior: the peritoneum covering the inferior vena cava; superior: the peritoneum covering the caudate lobe of the liver
The human body consists of biological systems, that consist of organs, that consist of tissues, that consist of cells and connective tissue. The history of anatomy has been characterized, over a long period of time, by a continually developing understanding of the functions of organs and structures in the body.
