1 Peristaltic contractions are always preceded by inhibition that, in the case of primary peristalsis, is called deglutitive inhibition. 2  Peristalsis in the striated muscle part of the esophagus is dependent on central mechanisms, involving sequential activation of vagal lower motor neurons in the vagal nucleus ambiguus.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.
