Auerbach plexus

anatomy
Also known as: myenteric plexus

Quick Summary

The Auerbach plexus, also known as the myenteric plexus, is a crucial part of the enteric nervous system within the walls of the gastrointestinal tract. It is located between the circular and longitudinal muscle layers of the esophagus, stomach, and intestines.12

The primary role of the Auerbach plexus is to control the involuntary muscle contractions, or peristaltic waves, that move food through the digestive system. It also helps regulate local muscle contractions for mixing and churning food, promotes the secretion of digestive juices, and controls the opening of sphincters to allow food passage. While extrinsic nerves also influence digestion, the basic functions of the Auerbach plexus can continue even without them.12
