Morphological Variation of Formation of Median and Musculocutaneous Nerve with Relation to the Axillary and Brachial Artery

Author(s): Jayakumari S*, rishnaveni Sharth and Asimitha Ramu


The knowledge of variant formation of brachial plexus and its branches are important for the surgeon and orthopedician pertaining to trauma and surgical procedures of the upper extremity. Current study was aimed to report variations in the formation of the median nerve with relation to the brachial artery. And also, the variation in the branching pattern of Musculo Cutaneous Nerve (MCN). Careful observation was made to note the formation and branching pattern of Median (MN) and Musculo Cutaneous Nerve (MCN) with the relation of axillary and brachial artery of formalin embalmed cadaver. In the present study, we noted the MN thus formed by 2 roots; lying behind the brachial artery. The coracobrachialis muscle was innervated by the direct branch from the lateral cord of brachial plexus. Unusual variant in the formation of median nerve in relation to the brachial artery may be important diagnoses to neurologist and surgeons.
