Which nerve travels through the arm?

Which nerve travels through the arm?

• A. Facial
• B. Radial
• C. Optic
• D. Vagus

Answer: (B)

Radial nerve is the one that travels through the arm. It courses down the posterior compartment of the arm, wraps around the humerus in the radial groove, and then continues into the forearm to supply many extensor muscles and sensation in part of the hand. The facial nerve stays in the face and parotid region, not in the arm; the optic nerve runs from the eye to the brain; and the vagus nerve travels in the neck and thorax into the abdomen. So the radial nerve is the nerve that passes through the arm.
