Mesentery

A membrane to invest and suspend internal organs.


A double layer peritoneum which attaches the small intestine and other abdominal organs to the abdominal wall.


Fold of peritoneum that holds abdominal organs (e.g., stomach, parts of the small intestine, spleen) to the posterior wall of the abdomen.


A supporting membrane that attaches various internal organs to the abdominal wall. The term is most frequently used to refer to the part of the peritoneum that enfolds most of the small intestine and attaches it to the rear wall of the abdominal cavity. The mesentery contains the arteries, veins, nerves, and lymphatic vessels that supply the large and small intestines.


A double layer of peritoneum attaching the stomach, small intestine, pancreas, spleen, and other abdominal organs to the posterior wall of the abdomen. It contains blood and lymph vessels and the nerves supplying these organs.


The double layer of peritoneal membrane which supports the small intestine. It is fan shaped, its shorter edge being attached to the back wall of the abdomen for a distance of about 15 cm (6 inches), while the small intestine lies within its longer edge, for a length of over 6 meters (20 feet). The terms mesocolon, mesorectum, etc., are applied to similar folds of peritoneum that support parts of the colon, rectum, etc.


Commonly, the peritoneal fold that encircles the small intestine and connects it to the posterior abdominal wall. Other abdominal organs, however, also have a mesentery.


The peritoneal membranes, or one of such membranes, encompassing a fold of tissue that connects the intestines and their appendages to the posterior wall of the abdominal cavity.


A peritoneal fold that fastens the intestines to the rear wall of the abdomen contains the mesenteric glands within its creases.
