What are the primary components of the musculoskeletal system?

• A. Muscle and nerves
• B. Support and move the body
• C. Process nutrients
• D. Regulate hormones

Answer: (B)

At its heart, the musculoskeletal system provides support for the body and enables movement. Bones form the framework that bears weight and protects organs, joints allow mobility, and muscles generate the forces that move bones when they contract. Tendons connect muscles to bones, transmitting that force, while ligaments stabilize joints. This combination lets you stand, walk, lift, and perform tasks. The other options point to other systems—nerves for signaling, digestion for nutrient processing, and endocrine glands for hormones—so they aren’t describing the main role of this system.
