Smooth muscle myosin

A smooth muscle is excited by external stimuli, which causes contraction. Each step is further detailed below. Smooth muscle may contract spontaneously (via ionic channel dynamics) or as in the gut special pacemakers cells interstitial cells of Cajal produce rhythmic contractions.
