The ulnar nerve arose as a continuation of medial cord, descended down along medial side of axillary and brachial artery. As the nerve travelled upper third of arm, it pierced the medial head belly of triceps muscle, passing through it for 4-5 cm ,emerged out of it to reach near the medial epicondyle. Then the nerve passed behind the medial epicondyle to follow its normal course and distribution. This kind of variation is not been described in the literature.
