Which type of muscle is under voluntary control?

Skeletal muscle is the type of muscle that is under voluntary control. This means that individuals can consciously contract and relax this type of muscle when they choose. Skeletal muscles are typically attached to the bones of the skeleton, and they are responsible for facilitating movement by pulling on bones during activities like walking, lifting, and other physical exertions.

The other muscle types—cardiac and smooth—do not operate under voluntary control. Cardiac muscle, found exclusively in the heart, operates involuntarily to pump blood throughout the body. Similarly, smooth muscle is found in various internal organs and is responsible for involuntary movements, such as those in the digestive tract and blood vessels. Since skeletal muscle is distinct in its voluntary nature, this makes it the correct choice in the context of the question regarding control.
