Which of the following is NOT part of the musculoskeletal system?

The musculoskeletal system comprises the muscles, bones, cartilage, tendons, and ligaments that work together to support the body, facilitate movement, and protect vital organs. Nerves are part of the nervous system, responsible for transmitting signals and facilitating communication between the brain and the rest of the body. While nerves may interact with the musculoskeletal system to coordinate muscle movements and provide sensory feedback, they do not form any part of the musculoskeletal structure itself, making them separate from muscles, bones, and cartilage, which are essential components of that system. Thus, identifying nerves as not part of the musculoskeletal system is accurate.
