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. ==Contents== * 1- [[transverse colon]] ( in the free margin ) * 2- [[middle colic vessels]] and their branches * 3- [[lymphatics]] and [[lymph node]]s * 4- [[autonomic]] nerve fibers * 5- [[extraperitoneal]] fatty tissue ==Additional images== <gallery> Image:Gray989.png|Schematic figure of the bursa omentalis, etc. Human embryo of eight weeks.
