ABSTRACT
The Brachial artery usually begins as the continuation of the Axillary Artery at the inferior border of the Teres Major muscle and terminates by bifurcating into radial and ulnar arteries in the cubital fossa. A case of unilateral bifurcation of the artery 7.5 cm distal to the inferior border of the Teres Major muscle in the proximal half of the right arm was identified in a northern Nigerian cadaver that was dissected by medical students of Usmanu Danfodiyo University, Sokoto. The Profunda Brachii, Superior Ulnar Collateral and Inferior Ulnar Collateral arteries arose from the relatively short brachial arterial trunk. Although the documented incidence of this anatomical variation is low in Nigeria, its concomitant widespread documentation in other parts of the world makes it a sufficiently important anatomical variation of the Brachial Artery, to warrant its being taught to students of Anatomy and Medicine. The knowledge of anatomical variations of the brachial artery and its branches is also important in radiological and clinical practice.
