A 39-year-old member asked:

Why would a peripheral nerve injury cause loss of both sensory and motor functions?

Combined nerve funct: The major peripheral nerves have both sensory and motor fibers. An injury to the nerve will cause loss of function to both the sensory and motor aspect innervated by that nerve. Your nerve needs to be evaluated by a hand surgeon if in the arms.
Dr. Michael McGonigal
General Surgery 39 years experience
Injury location: Although specific sensory branches go to skin and motor branches go to muscle, the main nerve trunks contain both. These large cables split off smaller branches that contain only sensory or motor nerve cells. If an injury occurs on the skin, sensantion nearby is affected. If a small motor nerve is injured, nearby muscles are paralyzed. But if a large nerve is injured, both can occur.
