The variation of the median nerve was observed incidentally during dissection of a 67 year-old male formalin-fixed Turkish cadaver assigned to the preclinical medical students at the Human Anatomy Laboratory of the Faculty of Meram Medicine, Selcuk University, Konya, Turkey. The median nerve was originating normally from the brachial plexus on proximal arm, but it received a communicating branch originated from the lateral cord on the middle arm. After lateral root of the median nerve leaved, the lateral cord bifurcated (lateral and medial branches) and both of them pierced the coracobrachial muscle. In previous studies, there were different definitions about connections. Knowledge of anatomic variations of the peripheral nervous system is helpful in explaining unusual clinical signs and permits correct interpretation of clinical neurophysiology.
