The radial nerve is one of three nerves that provide motor and sensory function to the arm. The nerve passes down the back of the upper arm. It then spirals outward and crosses the outside of the elbow before it winds its way down the forearm and hand.
The biceps muscle is located in the front of your arm. It is attached to the bones of the shoulder and elbow by tendons — strong cords of fibrous tissue that attach muscles to bones. Tears of the biceps tendon at the elbow are uncommon.
Tennis Elbow is caused by the inflammation of the tendons that attach the muscles of the wrist and fingers to the bone. This causes discomfort and swelling on the forearm.
Osteoarthritis of the elbow occurs when the cartilage surface of the elbow is worn out or is damaged. This can happen because of a previous injury such as elbow dislocation or fracture.
The “cubital tunnel” is a groove in the arm bone, with a thick ligament over the top of it, which forms a roof over the tunnel. Sitting in the tunnel is the ulnar nerve with some small blood vessels.
