The inner layer, the visceral peritoneum, is wrapped around the visceral organs, located inside the intraperitoneal space for protection. It is thinner than the parietal peritoneum. The mesentery is a double layer of visceral peritoneum that attaches to the gastrointestinal tract. There are often blood vessels, nerves, and other structures ...
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 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]
In human anatomy, the greater sac, also known as the general cavity (of the abdomen) or peritoneum of the peritoneal cavity proper, is the cavity in the abdomen that is inside the peritoneum but outside the lesser sac. A description of the greater sac in three dimensions.
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]
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 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.
The peritoneum is the serous membrane that surrounds several organs in the abdominopelvic cavity. The tunica vaginalis is the serous membrane, which surrounds the male gonad, the testis. The two layers of serous membranes are named parietal and visceral. Between the two layers is a thin fluid filled space. [4]
