The mesentery of the small intestine arises from the root of the mesentery (or mesenteric root) and is the part connected with the structures in front of the vertebral column. The root is narrow, about 15 cm long, 20 cm in width, and is directed obliquely from the duodenojejunal flexure at the left side of the second lumbar vertebra to the ...
The paramesenteric gutters (paramesenteric recesses or infracolic spaces) are two peritoneal recesses – spaces in the abdominal cavity between the colon and the root of the mesentery. There are two paramesenteric gutters; the left paramesenteric gutter and the right paramesenteric gutter.
Diagram showing the process by which the intestine rotates and herniates during normal development. From panel A to B (left-sided views), the midgut loop rotates 90° in a counterclockwise direction (caudal-to-rostral view), so that its position changes from midsagittal (A) to transverse (B1). The small intestine forms loops (B2) and slides ...

It surrounds the superior mesenteric artery, accompanies it into the mesentery, and divides into a number of secondary plexuses, which are distributed to all the parts supplied by the artery, viz., pancreatic branches to the ...
