What systems comprise the musculoskeletal system?

The musculoskeletal system is essential for movement, stability, and support in the body. It is primarily comprised of bones, joints, and muscles.

Bones form the rigid structure of the skeleton, providing support and protection for internal organs. Joints are the connections between bones that allow for a range of movements and flexibility. Muscles, particularly skeletal muscles, are responsible for generating force and facilitating movement by contracting and working in tandem with bones and joints.

The other options include components that are not central to the musculoskeletal system. For instance, while skin is vital for protection and sensation, it is part of the integumentary system, not the musculoskeletal system. Tendons and ligaments are important connective tissues that assist in the function of muscles and bones, but they are not standalone components of the musculoskeletal system as defined in this context. Similarly, cartilage, while present in joints and essential for joint function, is not one of the primary classifications in the musculoskeletal system.
