a. Propulsion - peristaltic waves move from the fundus toward the pylorus. Contractions are initiated by pacemaker cells (cells of Cajal) causing depolarisation and repolarisation of smooth muscle cells and hence rhythmic contraction. b. Grinding - the most vigorous peristalsis and mixing action occur close to the pylorus.

Signaling in Muscle Contraction

Calcium triggers contraction in striated muscle. (A) Actomyosin in striated muscle.(1) Striated muscle in the relaxed state has tropomyosin covering myosin-binding sites on actin.(2) Calcium binds to troponin C, which induces a conformational change in the troponin complex.This causes tropomyosin to move deeper into the actin groove, revealing the myosin-binding sites.

Figure 10.11 Skeletal Muscle Contraction (a) The active site on actin is exposed as calcium binds to troponin. (b) The myosin head is attracted to actin, and myosin binds actin at its actin-binding site, forming the cross-bridge. (c) During the power stroke, the phosphate generated in the previous contraction cycle is released.
