Corpus: Posterior vagal trunk

The posterior vagal trunk is a branch of the vagus nerve located behind the esophagus and formed from fibers of the esophageal plexus.

The posterior vagal trunk mainly consists of fibers from the right vagus nerve, a result of the stomach's rotation during embryonic development. It gives off several branches:

• Posterior gastric branches: These innervate the posterior surface of the stomach, with one prominent branch being the posterior nerve of the lesser curvature.
• Coeliac branches: These contribute to the formation of the coeliac plexus.
• Renal branches: These form the renal plexus along the renal artery.
