During routine dissection of a 70 year old male cadaver, we observed a variation in the course of musculocutaneous nerve and a communication between musculocutaneous nerve and median nerve in upper one third of arm. Musculocutaneous nerve arise from lateral cord of brachial plexus and does not pierce the coracobrachialis muscle and lies medial to it. Musculocutaneous nerve gives two muscular branches to coracobrachialis muscle and gives thick communicating branch to median nerve. These variations are important to surgeons while treating the traumatic injuries of axilla and arm.
