What Is the Mesentery?

The mesentery is part of the peritoneum that hangs and fixes the intestines. The peritoneum born on the left and right sides of the body meets on the dorsal and ventral sides of the intestine, forming the dorsal mesentery and ventral mesentery, respectively. A portion of the peritoneum is wrapped around the small and large intestines and connects the intestines to the back wall of the abdominal cavity.

The mesentery is suspended and fixed

Mesentery can be divided into small intestine

Most of the latter disappeared, and the dorsal mesentery remained, connecting the intestines to the spine. Therefore, the mesentery is made of two layers of peritoneum, so it is thin and tough. Most of the blood vessels and nerves leading to the intestine are distributed on it, with the differentiation, extension and tortuosity of the intestine, and the shape of the mesentery tends to be complicated. In mammals, there is only the small mesentery in the small intestine, and in the large intestine and

Irish researchers have recently determined that a new organ, the mesentery, is "hidden" in the human digestive system. ^[2]

Researchers reported in the British journal The Lancet Gastroenterology and Hepatology that in 2012, they found that the mesentery had a continuous structure through fine electron microscopy; in the past 4 years, they have continued to collect proof of the mesentery. Is further evidence of independent organs.

Calvin Coffey, a professor at the University of Limerick School of Medicine in Ireland who led the study, said in an interview with the media that the research paper has been peer-reviewed and that it can now be claimed that the previously unrecognized organ exists in the body. The anatomical descriptions that have been circulating more than a century ago are wrong. "

Thanks to this research, medical students have been studying mesentery as an independent organ since 2016. The world's most famous medical textbook, Grignard Anatomy, has also updated this latest definition.
