The person now have another on – Popular Mechanics

One of the first sketches of the mesentery (mesentery) is a complex structure that connects the intestine and some other organs with the rear wall of the abdominal cavity, belongs to the hand of Leonardo da Vinci. Great Italian depicted it as a single continuous structure. In the next century anatomists also portrayed the mesentery as a whole, carefully copying nature, but the modern idea of it as a few scattered structures were formed thanks to the work of anatomist of the late nineteenth century, Frederick Treves as (Frederick Treves), who concluded that the mesentery of some parts of the intestine exist apart.

In the modern medical literature about the mesentery is often referred to in the singular, calling it a fold of peritoneum, but equally often allocate individual sections of the mesentery of the intestine. Professor Calvin Coffey (Coffey Calvin) from the University of Limerick and surgeon Peter O’leary (Peter O’leary) of the Dublin Beaumont hospital has extensively studied the mesentery in patients who had surgery on the abdomen and on the corpses and came to the conclusion that the mesentery of a person — not a scattered pile of folds of connective and adipose tissue, individual for different sections of the intestine, as a whole.

Integrity, the constancy of cell and tissue structure and place in the body suggest that the mesentery is not just a method of attachment of the bowel to the peritoneum, as an independent body. However, the authority should have its own function; in addition, the development authority must be traceable to the same stages of ontogenesis of the organism. Understanding of the mesentery as a fragmented structure hindered the description of its embryonic development it was necessary to describe its emergence and growth in different places of the intestine. The findings of Coffey and O’leary greatly simplify the description of this process.

Mesentery, an organ, such as liver, brain or skin, scientists say. The most obvious function is the support of the intestine and prevent its falling into the cavity of the pelvis when a person stands. Coffey and O’leary suggested that mesentery evolved in humans as an adaptation to walking upright. However, proof of this hypothesis will require studies on analogues of other animals, they said.

In the future anatomists will answer many other questions related to functions and pathologies of the mesentery. Coffey is confident that over time the mesenteric science will become a full section of anatomy and medicine, like gastroenterology, neurology or Coloproctology.

Why is it important recognition of the body as a single entity? This apparently solely terminological subtlety can change a lot in science and medicine, says Coffey. The vision of the mesentery as the body with a special function will standardize certain surgical procedures in the abdominal cavity and even make abdominal surgery less invasive. Understanding organ function leads to the ability to see his pathology and treat them. The article by Coffey and O’leary with a detailed description of the mesentery as the body was published in the Lancet Gastroenterology & Hepatology, and her insights have moved to the classic textbook of human anatomy — “Anatomy of gray”.
