Abstract
Knowing the variations of the brachial plexus is of high importance during the surgery of axilla for surgeons. A rare case was observed in the left upper limb of a 55- year old female’s cadaver, during the routine dissection in Gilan Medical University.
In this case the musculocutaneous nerve that normally arises from the lateral cord of brachial plexus, originated from median nerve, without perforating coracobrachialis muscle, and was located between biceps brachii and brachialis muscles and innervated them.
Then, it pierces the deep fascia just below the elbow and extends as lateral cutaneous nerve of forearm. The nerve of coracobrachialis muscle is a branch directly isolated from lateral cord and enters into the muscle.
