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.
Generally, smooth muscle has to be able to contract continuously at a low level of intensity. The structure of smooth muscle enables it to function in this manner and differentiates it from other types of muscle found in the heart and musculature of the arms, legs, back and trunk.he nucleus of a smooth muscle cell, which contains the DNA, is located in the center of the cell, where the cell is widest. In the vicinity of the nucleus are various organelles, which are individual structures with specific cell functions.
