Which type of muscles is attached to bones and used for voluntary movement?

Skeletal muscles are the type of muscles that are attached to bones and are responsible for voluntary movement. These muscles are striated in appearance and can be consciously controlled, allowing individuals to perform a wide variety of activities, from walking and running to more complex movements like playing a musical instrument. Skeletal muscles work in pairs; when one muscle contracts, the opposing muscle relaxes to allow for smooth movement.

In contrast, visceral muscle refers to smooth muscle found in the walls of internal organs and blood vessels, which is not under voluntary control. Cardiac muscle is specialized muscle that makes up the heart and is also involuntary, working continuously to pump blood throughout the body. Muscle fibers are the basic cellular components of all types of muscle tissue, but they do not indicate a specific type of muscle nor specify the control mechanism. Thus, skeletal muscles are unique in their voluntary control and direct attachment to the skeleton, which enables intentional movements.
