Smooth muscle is fundamentally different from skeletal muscle and cardiac muscle in terms of structure, function, regulation of contraction, and excitation-contraction coupling. Smooth muscle cells known as myocytes, have a fusiform shape and, like striated muscle, can tense and relax.
Smooth muscle is found in your hollow organs and blood vessels. Like cardiac muscle, smooth muscle cannot be controlled consciously. Its actions are automatically controlled by your brain. Although smooth muscle is not able to contract as fast as skeletal muscle, it is designed to be very elastic.
