Dermatomes are specific areas of the skin that receive sensory innervation from a single spinal nerve. Each spinal nerve emerges from the spinal cord and branches to different parts of the body, providing sensation and motor control. On the hand, dermatomes are particularly important for sensory perception, fine motor skills, and coordination.
