Today' video covers rehab exercises for pain related to the three primary peripheral nerves that start in the neck and run down the arm.
The median nerve begins at the neck, like our the other peripheral nerves mentioned in the video (ulnar and radial) and receives contributions from many nerve roots (C5-T1). The nerve then courses down the arm, giving sensation to the palm side of the hand, the thumb, index, middle and the lateral half of the ring finger. It also provides motor input to most of the muscles that move our wrist and fingers into flexion (imagine making a fist).
The ulnar nerve is made up of the C8 and T1 neck branches and runs down the inside of the forearm to the pinky and inner side of the ring finger.
The radial nerve provides motor innervation to the triceps and the wrist/finger extensor muscles. The nerve also relays sensory input from most of the back of the hand and fingers (except the pinky and medial half of the ring finger).
