Where Does Peristalsis Occur. Peristalsis occurs throughout the digestive tract. It begins with the primary peristaltic wave in the esophagus as you swallow food from your mouth to the stomach. As food enters your stomach these muscular movements continue right through to your anus, where waste is eliminated from the body.
Control of peristalsis in the smooth muscle segment of the esophagus is more complicated than in the adjacent striated muscle segment. In the latter, the central nervous system not only initiates the primary and secondary peristaltic wave, but also completely controls the sequential nature of the contraction.sophageal peristalsis consists of sequential contraction of the circular muscles of the muscularis propria, which is largely mediated by acetylcholine. This sequential contraction serves to occlude the esophageal lumen and push the bolus aborally.
