ABSTRACT In the dissection of a 79-year-old Chinese male cadaver, communications were established on both sides between the median and musculocutanous nerves. The musculocutaneous nerve (mcn) was the continuation of the lateral cord. After piercing the coracobrachialis muscle, the mcn gave rise to a communicating branch which directed downwards medially and ended in the median nerve (mn) at the level of upper arm. In the left arm, the mn was formed by three roots: one medial root from the medial cord and two lateral roots from the lateral cord.
