Dorsal mesentery

Abdominal part of digestive tube and its attachment to the primitive or common mesentery. Human embryo of six weeks.

Latin	mesenterium dorsale commune
Gray's	p.1103

The portion of mesentery attached to the greater curvature of the stomach is named the dorsal mesentery (or dorsal mesogastrium, when referring to the portion at the stomach), and the part which suspends the colon is termed the mesocolon.

The dorsal mesogastrium develops into the greater omentum.

Mesentery in red. Dorsal mesentery is the lower part of the circuit. The upper part is ventral mesentery.
