The median nerve supplies cutaneous innervation to parts of the hand, primarily the lateral three and a half digits on the palmar side and their corresponding nail beds. Sensory fibers travel through the carpal tunnel to reach the thumb, index finger, middle finger, and the lateral half of the ring finger, allowing fine discrimination and tactile feedback essential for precision tasks. Damage or compression of the nerve, as in carpal tunnel syndrome, can lead to numbness, tingling, or weakness that affects grip strength and coordination. This sensory distribution helps clinicians test and localize median nerve injury. Cutaneous Innervation of the Median Nerve Skin of the Hand Diagram - Chart - diagrams and charts with labels.
