According to Hilton's law, what do nerves that innervate a muscle also innervate?

Hilton's law states that the nerves supplying a muscle also supply the skin overlying that muscle and the joints associated with it. This principle illustrates the relationship between the innervation of skeletal muscles and the sensory innervation of the surrounding structures.

The correct answer pertains to the nerves that innervate a muscle also innervating the overlying skin. This is notable because it emphasizes how sensory and motor functions are interconnected within a specific area of the body. The skin, being a sensory organ, receives proprioceptive signals from the same nerve pathways that control muscle movement, which aids in coordinating actions and responses to stimuli.

While options like underlying bones, adjacent muscles, and joint ligaments may involve some degree of neurological interaction, they don't encompass the essence of Hilton's law, which specifically highlights the dual function of motor and sensory innervation provided by the same nerve.
