Which organ system includes bones and joints and supports movement?

• A. Nervous
• B. Musculoskeletal
• C. Lymphatic
• D. Integumentary

Answer: (B)

The musculoskeletal system is responsible for movement because it combines the skeletal framework (bones and joints) with the muscles that move them. Bones provide a sturdy structure and protection, while joints allow different bones to move relative to each other. Muscles attach to bones via tendons and generate motion by pulling on the bones across joints, enabling walking, running, and everyday actions, as well as maintaining posture. The nervous system coordinates and controls these actions, but it does not itself consist of bones and joints; the lymphatic and integumentary systems have roles in immunity and protection of the body’s surface, respectively. So the system that includes bones and joints and supports movement is the musculoskeletal system.
