The musculoskeletal system includes bones and which type of muscle?

• A. Cardiac muscles
• B. Smooth muscles
• C. Voluntary (Skeletal) muscles
• D. Involuntary muscles

Answer: (C)

Skeletal muscles are the muscles that move the bones, and they are under voluntary control, meaning you decide when to use them. The musculoskeletal system combines bones with these skeletal muscles to enable movement, support, and posture. Cardiac muscle forms the heart and works automatically (involuntary), while smooth muscle is found in the walls of organs and vessels and is also involuntary. Because the question pairs bones with the muscle type that moves them, the correct fit is skeletal muscle—the voluntary type.
