Esophageal Plexus

The Esophageal Plexus of nerves is formed by the right vagus and left vagus nerves . The right and left vagus nerves leave the pulmonary plexuses and redivide to form a network of nerves which enclose and infiltrate the esophagus. The plexus receives contributions from the greater splanchnic nerve, and from the thoracic sympathetic chain(or ganglia) between the sixth and tenth thoracic levels. The right and left vagus nerves lose their identity in the esophageal plexus. The esophageal plexus enters the abdomen (esophageal hiatus) anterior and posterior to the esophagus and toward its right side. No longer representative of left vagus and right vagus, they are designated as anterior vagal and posterior vagal trunks.
