The Ulnar Nerve runs around the inner side of the elbow in a groove just behind a bony prominence (medial epicondyle). The nerve, where it lies in the groove, is covered by a layer of tissue which forms a tunnel called the Cubital Tunnel. The ulnar nerve is important as it controls the small muscles in the hand which are particularly important for fine movements such as doing up buttons, gripping and holding cutlery. It is also responsible for normal feeling in the little and ring fingers.
