Detailed explanation-1: -The myenteric plexus is principally responsible for the peristaltic movement of the bowels. While it can act independently from the central nervous system, it receives innervation from the autonomic nervous system, connecting the central and enteric nervous systems.

Detailed explanation-2: -The myenteric plexus, also known as Auerbach’s plexus, is located between the longitudinal and circular muscle layers of the esophagus, stomach, and small and large intestine. The submucosal plexus, also known as Meissner’s plexus, is situated in the submucosal region between the circular muscle and mucosa.

Detailed explanation-3: -Auerbach plexus (named after Leopold Auerbach (1828-1897)), also known by the name of myenteric plexus, is a group of ganglia that run throughout the entire gastrointestinal tract and innervate its multiple layers of smooth muscle.

Detailed explanation-4: -…the gut, is called the Auerbach, or myenteric, plexus. Neurons of this plexus regulate peristaltic waves that move digestive products from the oral to the anal opening. In addition, myenteric neurons control local muscular contractions that are responsible for stationary mixing and churning.

Detailed explanation-5: -Overview. Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.
