Which muscle type has voluntary movement?

Which muscle type has voluntary movement?

• A. Skeletal
• B. Cardiac
• C. Smooth
• D. All of the above

Answer: (A)

Voluntary movement is produced by skeletal muscle. These muscles attach to bones and contract under conscious control, driven by the somatic (voluntary) nervous system, which lets you decide to move your arms, legs, or other body parts. Cardiac muscle, found in the heart, and smooth muscle, lining organs and blood vessels, contract automatically under the autonomic nervous system and are not under conscious control. So the only muscle type with voluntary movement is skeletal muscle, not the others.
