Auerbach's plexus, also known as the myenteric plexus, is a network of nerve fibers located between the layers of the muscularis externa in the gastrointestinal tract. It plays a crucial role in regulating the movement of the intestines, coordinating peristalsis, and controlling digestive processes. This plexus is part of the enteric nervous system, which governs the function of the digestive system independently of the central nervous system. The myenteric plexus contains a variety of neurons and glial cells that communicate with each other to ensure smooth muscle contractions occur in a coordinated manner. Dysfunction in Auerbach's plexus can lead to gastrointestinal disorders, such as achalasia or Ileus, affecting the normal movement of food through the digestive tract.
