| musculospiral nerve | <anatomy, nerve> A major nerve of the upper extremity. In humans the fibres of the radial nerve originate in the lower cervical and upper thoracic spinal cord (usually c5 to t1), travel via the posterior cord of the brachial plexus, and supply motor innervation to extensor muscles of the arm and cutaneous sensory fibres to extensor regions of the arm and hand.
