Variation in the termination of musculocutaneous nerve

A variation of the musculocutaneous nerve was observed during routine dissection for first year medical students, in a 67 year old embalmed male cadaver. The termination of musculocutaneous nerve in left upper limb was variable. After piercing the coracobrachialis muscle, musculocutaneous nerve divided into lateral cutaneous nerve of the forearm and gave an accessory branch that joined with median nerve, lateral to the insertion of the coracobrachialis muscle. Knowledge of these variations is of great importance to surgeons and orthopaedicians who do surgical interventions in that region.
