Anatomy, Shoulder and Upper Limb, Hand Cutaneous Innervation

Excerpt

Three independent nerves supply the cutaneous innervation of the hand (see Image. Hand Cutaneous Innervation). From lateral to medial, these nerves include the superficial branch of the radial, median, and ulnar nerve. These peripheral nerves originate from the C5 to T1 levels of the spinal column. The sensory distribution discussed here includes both the ventral and dorsal aspects of the hand, ending proximally at the level of the wrist. Also briefly discussed here are a set of muscles innervated by these nerves as they supply the cutaneous innervation of the hand.
