Which body system provides the framework of the body, gives shape, and enables movement while protecting organs?

• A. Musculoskeletal system
• B. Nervous system
• C. Circulatory system
• D. Endocrine system

Answer: (A)

Movement and structure come from the musculoskeletal system. Bones provide the framework and shape of the body, giving it support. Muscles attach to bones and contract to produce movement, while joints allow the range of motion. Bones also protect vital organs: the skull guards the brain and the rib cage shields the heart and lungs. This system is distinct from the nervous system, which coordinates movement and sensation, the circulatory system that transports blood, and the endocrine system that regulates body processes. In practice, nurses assess posture, strength, and range of motion, and recognize how the skeleton and muscles support function and protection.
