transverse mesocolon

[mez′ōkō′lən]
a broad fold of the peritoneum connecting the transverse colon to the dorsal wall of the abdomen. It is continuous with the greater omentum along the ventral surface of the transverse colon and contains between its layers the vessels that supply the transverse colon. Its two layers diverge along the anterior border of the pancreas. Compare mesentery proper, sigmoid mesocolon.
