AbstractDuring gross dissection of right upper limb of a 50 yrs old female cadaver, it was observed that the lateral cord followed its usual path without giving rise to the musculocutaneous nerve, and continued as the lateral root of the median nerve, and a small loop of fibres from lateral cord itself joined the median nerve. There was a connecting band of nerve fibres between lateral and medial cord. The biceps brachii, brachialis and coracobrachialis muscles were innervated by branches that emerged from the median nerve in the arm, longest of these took a curvilinear lateral path between the biceps brachii and brachialis muscles, and appear on the lateral margin of the forearm. It then followed a descending path over the brachioradialis muscle as the lateral antebrachial cutaneous nerve
