Fig: Regions of ureteral peristalsis Regulation of ureteral peristalsis WebSlow waves generated in interstitial cells of Cajal spread to the surrounding smooth muscle cells and control motility. Description [ edit] In the human enteric nervous system, the slow-wave threshold is the slow-wave potential which must be reached before a slow wave can be propagated in gut wall smooth muscle. Peristalsis is a radially symmetrical contraction and relaxation of muscles that propagate in a wave down a tube, in an anterograde direction. Peristalsis is progression of coordinated contraction of involuntary circular muscles, which is preceded by a simultaneous contraction of the longitudinal muscle and relaxation of the circular muscle in the lining of the gut. subaru off road vehicles
