The misty mesentery sign is a non-specific radiological finding characterized by increased attenuation within the mesenteric fat on computed tomography (CT) imaging. It reflects pathological processes that result in infiltration, edema, or increased cellularity within the mesentery, often in association with inflammation and adjacent lymphadenopathy. [1]
The mesentery of the small intestine arises from the root of the mesentery (or mesenteric root) and is the part connected with the structures in front of the vertebral column. The root is narrow, about 15 cm long, 20 cm in width, and is directed obliquely from the duodenojejunal flexure at the left side of the second lumbar vertebra to 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).
Watershed area is the medical term referring to regions of the body, [1] that receive dual blood supply from the most distal branches of two large arteries, such as the splenic flexure of the large intestine. The term refers metaphorically to a geological watershed, or drainage divide, which separates adjacent drainage basins. For example, the ...
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 ...
Initially, the gut tube from the caudal end of the foregut to the end of the hindgut is suspended from the dorsal body wall by dorsal mesentery. Ventral mesentery, derived from the septum transversum, exists only in the region of the terminal part of the esophagus, the stomach, and the upper portion of the duodenum. [2]
An ocularist specializes in the fabrication and fitting of ocular prostheses for people who have lost an eye or eyes due to trauma or illness. [1] The fabrication process for a custom made eye typically includes taking an impression of the eye socket, shaping a plastic shell, painting the iris, and then fitting the ocular prostheses.
