Abstract

During routine cadaveric dissection of the flexor compartment of the right arm, multiple supernumerary muscles were observed in a 56-year-old male cadaver. There were three supernumerary muscles took taking origin independently from the humerus distally to the insertion of coracobrachialis muscle. The upper two supernumerary muscles were attached to the common tendon of the biceps brachii muscle and considered as its additional heads. The third supernumerary muscle passed between the biceps brachii and brachialis muscles, then crossed obliquely the brachial artery and median nerve nearing cubital fossa to get inserted in to the radial side of the humeral head of the pronator teres. The clinical significance of the above variations is discussed (Fig. 1, Ref. 16).
