Skeletal muscle is the type that moves the skeleton. These muscles attach to bones via tendons and pull on the bones when they contract, creating the joint motions we consciously perform. They are under voluntary control, meaning you decide when to move them, and they have a striated appearance with fibers arranged for strong, rapid contractions. Cardiac muscle drives the heart’s pumping action and isn’t attached to bones, while smooth muscle encircles hollow organs and blood vessels to regulate things like flow and digestion—both operate involuntarily. Saying simply “muscle tissue” is too broad, since it includes all muscle types; the one responsible for moving the skeleton specifically is skeletal muscle.
