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 vs Cardiac Muscle. Most often, the term muscles mean the skeletal muscles for many of you, but there are two more types with a greater importance for survival of the animal. Smooth and cardiac muscles are the other two types. Cardiac muscles are striated, but smooth muscles are non-striated. â¢ Each cardiac muscle cell has one or more nuclei, but the smooth muscle cells are single nucleated. â¢ Cardiac muscle cells are often branched, but smooth cells are non-branched.
