Posterior nerve of lesser curvature

Posterior nerve of lesser curvature comes off from the posterior vagal trunk.

The posterior vagal trunk–as it passes through the esophageal hiatus of the diaphragm–gives off several branches near the gastroesophageal junction. These include the criminal nerve of Grassi (to the fundus), celiac branches, posterior gastric branches and the posterior nerve of lesser curvature. Amongst them, the posterior nerve of lesser curvature continues to descend along the lesser curvature of the stomach, sandwiched between the anterior and posterior peritoneal layers of the lesser omentum. It innervates the lesser curvature of the stomach and goes behind the stomach to innervate the posteroinferior gastric region.
