Superior and inferior duodenal fossæ. (Transverse mesocolon visible at top center.)
Diagram showing the lines along which the peritoneum leaves the wall of the abdomen to invest the viscera. (Transverse mesocolon labeled at center right.)
It is continuous with the two posterior layers of the greater omentum, which, after separating to surround the transverse colon, join behind it, and are continued backward to the vertebral column, where they diverge in front of the anterior border of the pancreas.
This fold contains between its layers the vessels which supply the transverse colon.
Transverse mesocolon is a derivative of dorsal mesentery in the embryo.
