Anatomical terms of neuroanatomy

The anterior vagal trunk is one of the two divisions (the other being the posterior vagal trunk) into which the vagus nerve splits as it passes through the esophageal hiatus to enter the abdominal cavity. [1] The anterior and posterior vagal trunks represent the inferior continuation of the esophageal nervous plexus inferior to the diaphragm. [2] The majority of nerve fibres in the anterior vagal trunk are derived from the left vagus nerve. [1]

Contents

The anterior vagal trunk is responsible mainly for providing parasympathetic innervation to the lesser curvature of the stomach, pylorus, gallbladder, and biliary apparatus. [1]

Clinical significance
