Hilton's Law states that the joint capsule, the muscle moving in that joint, and what else have the same nerve supply?

Hilton's Law posits that the nerve supplying a joint also innervates the muscles that move the joint as well as the skin that lies over the muscles' insertion. This principle highlights the relationship between nerves, muscles, joints, and the overlying skin. Therefore, the correct answer is that the skin overlying the insertion of the muscles shares the same nerve supply as the joint capsule and the muscle moving the joint.

Understanding Hilton's Law is essential for recognizing how injuries or conditions affecting a joint can also lead to sensations in the skin overlying that area. This relationship can provide valuable insights for assessing and treating joint-related issues, as it can explain referred pain patterns and sensory changes associated with musculoskeletal injuries.

The tendon of the muscle, the bone at the joint, and synovial fluid do not share the same nerve supply in the same way that skin does with the associated muscle and joint. While they are related to the function of the joint, they do not exhibit the same direct innervational relationship defined by Hilton’s principle.
