Mesentery – The New Organ can now change the history of Human Anatomy

Although the scientific research is advancing in recent times there are many things which still remained unexplored. In biomysteries lets me introduce you to a new organ that remained unexplored. Researchers from Ireland identified a part of our digestive tract, that was long considered to be a mere tissue is actually a full grown organ that connects abdomen to intestine. This new organ has shook the medical fields researchers to look into new understanding about bowel disease and other gut diseases.

The new organ is named Mesentery which was long been known but never considered to be an organ. It has a complex and fragmented appearance. The anatomic description of mesocolon dates back in 1885 when Sir Frederick Treves studied human mesentery on 100cadavers. But until recently from a study carried out from University of Limeric has concluded Mesentery as a full grown organ.

Professor J. Calvin Coffey who is the professor of Surgery explained how 100years of anatomical understanding was incorrect. Some of the recent text books now need to be updated as the number of organs in our body has officially changed into 79. Although re-classification would not affect directly but will provide a clear picture of many unknown facts of bowel diseases.
