Irish scientists have classified a new organ in human body while proving “the anatomic description that had been laid down over 100 years of anatomy was incorrect.” The latest discovery is evidence that science continuously questions itself, and by questioning it develops its capacity to find facts.
The mesentery, which attaches the intestine to the abdomen, is the 79th organ in the human body.
Science Alert said, the mesentery was described by Leonardo da Vinci; but scientists have long assumed it was a series of multiple structures, and that assumption led them to say that that was not an organ.
However, its microscopic level examinations show that it is a self-contained structure, which meets the definition of an organ.
Scientists are now trying to figure out the exact way the mesentery works. This could lead to better treatment for digestive and abdominal diseases.
“The next step is the function,” said J. Calvin Coffey, lead researcher. “If you understand the function you can identify abnormal function, and then you have disease.” Coffey says the classification of the mesentery as an organ leads to a “whole new area of science.”
“The mesentery should be subjected to the same investigatory focus that is applied to other organs and systems,” researchers conclude in their study, published in the November issue of the Lancet Gastroenterology & Hepatology.
