What are the differences and similarities between skeletal smooth and cardiac muscles?

Answer 1

Skeletal muscles are voluntary muscles, meaning that they are used in actions which a person consciously controls, such as lifting a dolphin or biting into a book.

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.

Answer 2

Neither one are voluntary , skeletal muscle is the only type that is voluntary

smooth muscle - has no striations, a single centrally located nucleus, short tapered fibers, slow contractions that are resistant to fatigue and are located on the walls of hollow visceral organs and blood vessels




cardiac muscle - has striations, single centrally located nucleus, short and branching fibers, rhythmic contractions that are resistant to fatigue and are located on the wall of the heart
