What best describes the composition of the musculoskeletal system?

• A. It provides the body's basic frame support and enables movement.
• B. It consists mostly of the muscles, the bones, and other minor systems.
• C. It regulates immune responses.
• D. It controls the endocrine system.

Answer: (B)

The key idea here is what the musculoskeletal system is made of. Its framework and movement come mainly from two big components: bones that provide structure and leverage, and muscles that generate force. Along with these, connective tissues like tendons, ligaments, cartilage, and the joints enable us to move smoothly. The statement that best describes composition says it consists mostly of the muscles and bones, with other minor components included. That matches the reality that bones and muscles are the primary building blocks, while the connective tissues and joints round out the system. The other choices describe functions or other bodily systems (immune or endocrine), which aren’t about what the musculoskeletal system is made of.
