Nerve variations are always a great challenge to the surgeons, anaesthetists and neurologists. The precise knowledge of variations may help to avoid injuries during surgical and anaesthatic procedures in the region of axilla, arm and forearm. Musculocutaneous nerve is a branch of lateral cord of brachial plexus. It pierces the corachobrachialis muscle and runs in between the biceps and brachialis muscles. After giving off muscular branches, the nerve pierces the deep fascia about 2-3cm above the elbow and continues as lateral cutaneous nerve of forearm. We observed that the lateral cutaneous nerve of forearm is found to be arising from the median nerve. The musculocutaneous nerve terminated after supplying the muscles of the arm without giving any communicating branch to the median nerve. The reminding of this type of variation is also important while performing the surgeries on the forearm.
