The transverse mesocolon is a broad, meso-fold of peritoneum, which connects the transverse colon to the posterior wall of the abdomen.
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.
