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 muscles are used in involuntary actions, which a person doesn't consciously control, like digesting food. Cardiac muscles are found in the heart, and control the actions of the heart, like pumping blood.They are a form of smooth muscle.They're all similar in that they're all a type of muscle, all of them contract and expand to complete their jobs, and they all control various forms of movement. cardiac and skeletal muscles have one thing in common, that is they are both striated in contrast to the smooth muscles commonly found in the GIT. however the main diffe â¦ rence between them is that cardiac muscles function involuntarily while skeletal muscles are under conscious control.
