The esophageal plexus (oesophageal plexus in British-English) is formed by nerve fibers from two sources, branches of the vagus nerve, [1] [2] and visceral branches of the sympathetic trunk. [ 3 ] [ 4 ] The esophageal plexus and the cardiac plexus contain the same types of fibers and are both considered thoracic autonomic plexus .
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 esophagus also lies in front of parts of the hemiazygos veins and the intercostal veins on the right side. The vagus nerve divides and covers the esophagus in a plexus. [4] Constrictions The esophagus is constricted in three places. [inconsistent] The esophagus has four points of constriction.
The posterior vagal trunk is one of the two divisions (the other being the anterior 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 together represent the inferior continuation of the esophageal nervous plexus inferior to the ...

The plexus is formed in part by the greater and lesser splanchnic nerves of both sides, and fibers from the anterior and posterior vagal trunks. The celiac plexus proper consists of the celiac ganglia with a network of interconnecting fibers. The aorticorenal ganglia are often considered to be part of the celiac ganglia, and thus, part of the ...
Human anatomy is the scientific study of the morphology of the adult human. It is subdivided into gross anatomy and microscopic anatomy . Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision.
The fibers are carried by both the anterior and posterior vagal nerves. The myenteric plexus is the major nerve supply to the gastrointestinal tract and controls GI tract motility. [1] According to preclinical studies, 30% of myenteric plexus' neurons are enteric sensory neurons, thus Auerbach's plexus has also a sensory component. [2] [3]
