  1. mesocolon

    The mesentery is an organ that attaches the intestines to the posterior abdominal wall in humans and is formed by the double fold of peritoneum. It helps in storing fat and allowing blood vessels, lymphatics, and nerves to supply the intestines, among other functions.The mesocolon was thought to be a fragmented structure, with all named parts—the ascending, transverse, descending, and sigmoid mesocolons, the mesoappendix, and the mesorectum—separately terminating their insertion into the posterior abdominal wall. However, in 2012, new microscopic and electron microscopic examinations showed the mesocolon to be a single structure derived from the duodenojejunal flexure and extending to the distal mesorectal layer. Thus, the mesentery is an internal organ.


  1. mesocolon

    The mesocolon is a fold of peritoneum (a membrane that lines the abdomen and surrounds the abdominal organs) that attaches the colon (part of the large intestine) to the posterior abdominal wall. It helps to keep the colon in place, preventing it from moving around within the abdomen. The mesocolon contains blood vessels, lymph vessels, and nerves that supply the colon.
