Clarifications of the mesenteric anatomy have facilitated a clearer understanding of diseases involving the mesentery, examples of which include malrotation and Crohn's disease (CD). In CD, the mesentery is frequently thickened, rendering hemostasis challenging. In addition, fat wrapping—creeping fat—involves extension of mesenteric fat ...
In human anatomy, the inferior mesenteric artery (IMA) is the third main branch of the abdominal aorta and arises at the level of L3, supplying the large intestine from the distal transverse colon to the upper part of the anal canal.
In zoology, a mesentery is a membrane inside the body cavity of an animal. The term identifies different structures in different phyla : in vertebrates it is a double fold of the peritoneum enclosing the intestines; in other organisms it forms complete or incomplete partitions of the body cavity, whether that is the coelom or, as in the ...
The mesothelium is a membrane composed of simple squamous epithelial cells of mesodermal origin, [2] which forms the lining of several body cavities: the pleura (pleural cavity around the lungs), peritoneum (abdominopelvic cavity including the mesentery, omenta, falciform ligament and the perimetrium) and pericardium (around the heart).
The mesenteric lymph nodes or mesenteric glands are ... This article incorporates text in the public domain from page 709 of the 20th edition of Gray's Anatomy (1918)
In human anatomy, the superior mesenteric artery (SMA) is an artery which arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies blood to the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.
The inferior mesenteric lymph nodes consist of: (a) small glands on the branches of the left colic and sigmoid arteries (b) a group in the sigmoid mesocolon, around the superior hemorrhoidal artery (c) a pararectal group in contact with the muscular coat of the rectum
The mesentery is a double layer of visceral peritoneum that attaches to the gastrointestinal tract. There are often blood vessels, nerves, and other structures between these layers. There are often blood vessels, nerves, and other structures between these layers.
