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 position of the intestines, narrow mesentery and Ladd's bands can contribute to several severe gastrointestinal conditions. The narrow mesentery predisposes some cases of malrotation to midgut volvulus, a twisting of the entire small bowel that can obstruct the mesenteric blood vessels leading to intestinal ischemia , necrosis , and death ...
The peritoneum is the serous membrane forming the lining of the abdominal cavity or coelom in amniotes and some invertebrates, such as annelids.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 related term mesenteric ischemia or small intestine ischemia generally defined as ischemia of the small bowel specifically. [40] It has also been defined as poor circulation in the vessels supplying blood flow to any or several of the mesenteric organs, including the stomach, liver, colon and intestine.
The gastrointestinal tract (GI tract, digestive tract, alimentary canal) is the tract or passageway of the digestive system that leads from the mouth to the anus.The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus, stomach, and intestines.
The duodenum and the jejunum are the first and second parts of the small intestine, respectively.The suspensory muscle of the duodenum marks their formal division. [2] The suspensory muscle arises from the right crus of the diaphragm as it passes around the esophagus, continues as connective tissue around the stems of the celiac trunk (celiac artery) and superior mesenteric artery, passes ...
A key principle in the dissection of human cadavers (sometimes called androtomy) is the prevention of human disease to the dissector.Prevention of transmission includes the wearing of protective gear, ensuring the environment is clean, dissection technique [2] and pre-dissection tests to specimens for the presence of HIV and hepatitis viruses.

The stomach is also called the gaster (Greek belly) or venter from which we have the adjective gastric applied to structures related to the organ. [3] The stomach is a muscular, hollow organ in the upper gastrointestinal tract of humans and many other animals, including several invertebrates.
