A smooth muscle is excited by external stimuli, which causes contraction. Each step is further detailed below. Inducing stimuli and factors. Smooth muscle may contract spontaneously (via ionic channel dynamics) or as in the gut special pacemakers cells interstitial cells of Cajal produce rhythmic contractions.
Single-unit smooth muscle, commonly called visceral muscle because it is in the walls of all hollow organs except the heart, is far more common. All the smooth muscle characteristics described so far pertain to single-unit smooth muscle.his propulsive action is called peristalsis.

Smooth muscle contraction also accounts for the constricted breaking of asthma and for stomach craps.
