Head and Arm Nerves

The arm is one of the body’s most complex and frequently used structures. It contains three main nerves running past the elbow and wrist to the hand: median nerve, ulnar nerve, radial nerve. The brachial plexus is a group of nerves that control the muscles of the shoulder, arm, forearm and hand. These same nerves also provide sensation (feeling) to the whole upper limb. They are susceptible to injury, which can lead to pain and loss of function due to nerve compression. Surgery can decompress nerves and reverse the damage.
