Mesentery

From Freepedia

In anatomy, a mesentery is a part of the peritoneum that connects an internal organ, such as the small intestine, to the abdominal wall.
THE mesentery refers to the mesentery responsible for connecting the small intestines to the backwall. It does this by long veins branching out directly out of the center of the sack which enclose the organs. The organ receives its blood supply, lymph drainage and nerves through the mesentery.

In vertebrates, the mesentery is attached to the back of the abdominal wall parallel to the spine and folding occurs after this development in the embryo, so that the intestines are free to move against one another without friction. However, as these organs can move within the cavity relatively freely, the brain cannot map sensation accurately, so sensation is usually referred to the midline.

In invertebrate animals, the term mesentery is also used for any tissue that divides the body cavity (coelom) into partitions.
