Anatomical terminology

Ventral mesentery is the part of the peritoneum closest to the navel.

Development[edit]

The cephalic portion of the septum transversum takes part in the formation of the diaphragm, while the caudal portion into which the liver grows forms the ventral mesentery (or ventral mesogastrium, when referring to the portion at the stomach).[1]

The lesser omentum is formed, by a thinning of the mesoderm or ventral mesogastrium, which attaches the stomach and duodenum to the anterior abdominal wall. By the subsequent growth of the liver this leaf of mesoderm is divided into two parts, viz., the lesser omentum between the stomach and liver, and the falciform and coronary ligaments between the liver and the abdominal wall and diaphragm.[1]

Mesentery in red. Ventral mesentery is the upper part of the circuit. The lower part is dorsal mesentery.
