WebContractions follow an action potential. 4. In the fed state two types of motility occur, segmentation (or mixing) and peristalsis. In the fasted state, the migrating motor complex sweeps the tract clean. 5. Tonic contractions occur at the sphincters and when there is no motility within the tract. http://www.vivo.colostate.edu/hbooks/pathphys/digestion/herbivores/horses.html

Segmentation contractions (or movements) are a type of intestinal motility. Unlike peristalsis, which predominates in the esophagus, segmentation contractions occur in the large intestine and small intestine, while predominating in the latter. While peristalsis involves one-way motion in the caudal direction, segmentation contractions move chyme in both directions, which allows greater mixing with the secretions of the intestines. Segmentation involves contrac… Webperistalsis vs segmentation Peristalsis propels food forward, smooth muscle in front of food relaxes, and behind food contracts the movement.
