Detailed explanation-2: -…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-3: -Meissner’s and Auerbach’s plexus are two enteric nerve plexus. They are intricate layers of nervous tissue. They control movements in the esophagus, stomach, and intestines.
