The brachial artery is the extension of the axillary artery starting at the lower margin of the teres major muscle and is the major artery of the upper extremity. The brachial artery reaches the cubital fossa and bifurcates into the radial and ulnar artery. The ulnar artery further gives short trunk called common interosseous artery which in turn divided into anterior and posterior interosseous. In this study we observed that the anterior interosseous artery instead of arising from the ulnar artery it took origin from brachial artery and there was absence of common interosseous artery. Ulnar artery is very much thin which is continuing as its normal course in forearm as well in hand
