Peristalsis longitudinal and circular muscles
WebIt comprises layers of smooth muscle in longitudinal and circular orientation that also helps with continued bowel movements ( peristalsis) and the movement of digested material out of and along the gut. In between the two layers of muscle lies the myenteric plexus (also called Auerbach's plexus). The serosa / adventitia are the final layers. WebPeristalsis is a common mode of locomotion of many soft-bodied animals (e.g., earthworms, sea cucumbers, caterpillars, and snails). Alternating waves of muscle contraction and relaxation move along the body, anchoring the body to the substratum only in widened regions (Figure 6 ).
