Peritoneum anatomy. The peritoneum is a continuous membrane which lines the abdominal cavity and covers the abdominal organs abdominal viscera. The peritoneum consists of two layers. In mammals the serous membrane that lines the cavity of the abdomen and that is folded over the viscera.

The peritoneum is the serous membrane forming the lining of the abdominal cavity or coelom in amniotes and some invertebrates such as annelids. Peritoneum large membrane in the abdominal cavity that connects and supports internal organs. Greek peritonaion stretch around The peritoneum is a continuous serous membrane which lines the abdominal cavity and covers the abdominal organs.

All abdominal organs have a characteristic position in relation to the peritoneum. It acts to support the viscera and provides a pathway for blood vessels and lymph. Its made when parietal peritoneum reflects from the abdominal wall to the viscera.

Its surface area is approximately 1-2 m 2. Visceral peritoneum an inner layer which lines the abdominal organs. Although the peritoneal area is commonly suggested to be similar to the body surface area.

The membrane that attaches the intestines to the wall of the abdomen and maintains their position in the abdominal cavity to supply them with blood vessels nerves and lymphatics. The omentum which hangs in front of the stomach and intestine. The peritoneum or peritoneal cavity is a large complex serous membrane that forms a closed sac within the abdominal cavity.

It covers most of the intra-abdominal or coelomic organs and is composed of a layer of mesothelium supported by a thin layer of connective tissue. The peritoneum consists of the parietal peritoneum a heterogeneous serous semi-permeable membrane that lines the abdominal wall and the visceral peritoneum which covers the abdominal organs Figure 1. The parietal peritoneum lines the diaphragm abdominal walls and pelvic cavity.

Knowledge of peritoneal anatomy is essential for radiologists to accurately identify the spread of tumors and fluid collections across the peritoneal spaces at cross-sectional imaging. Two folds are of primary importance. The peritoneum is a large serous membrane with both epithelial and mesenchymal features and is essential for maintaining an intra-abdominal homeostatic equilibrium.

The peritoneum helps support the organs in the abdominal cavity and also allows nerves blood vessels and lymph vessels to pass through to the organs. The peritoneal folds connect the various organs to the abdominal wall or to each other. The peritoneal folds include the omenta greater and lesser omentum the mesentery and the ligaments.

Parietal peritoneum an outer layer which adheres to the anterior and posterior abdominal walls. The peritoneum is a complex membrane which forms folds covers various abdominal organs and contains neurovascular structures within its folds. It is composed of many folds that pass between or around the various organs.

Anatomically the peritoneum is divided into a parietal and visceral peritoneum. This video tutorial covers the concepts of serous membranes peritoneum parietal peritoneum mesentery visceral peritoneum peritoneal cavity and peritone. It is a potential space between the parietal peritoneum lining the abdominal wall and the visceral peritoneum enveloping the abdominal organs.

It acts to support the viscera and provides pathways for blood vessels and lymph to travel to and from the viscera. The peritoneum is a continuous glistening and slippery transparent serous membrane lining the abdominopelvic cavity and investing the viscera of the abdomen and pelvis. One layer lines the cavity and the other layer lines the organs.

The parietal peritoneum lines the abdominal wall and. The peritoneal cavity is the largest serosal cavity in the body with a surface area of approximately 1 to 2 m 2. This determines their accessibility mobility and interconnection.

The peritoneum is a membrane made up of two layers. The peritoneum is the membrane that lines the abdomen and the abdominal organs. And the mesentery which.

Anatomy of the Peritoneum See online here The peritoneum is a serous membrane formed by connective tissue originating from the mesoderm and conﬁrmed by the parietal layer which cover the internal walls of the abdomen and the visceral layer which cover the abdominal viscera providing support protection and nutrition. The peritoneum plays a central role in the pathogenesis of a number of disorders. Within the cavity of the peritoneum.

It is difficult to identify normal peritoneal folds and ligaments at imaging.
