Median nerve is one of the terminal branches of the brachial plexus associated with several variations most of which are reported in the literature. Some of these variations include abnormal communications with other nerves such as musculocutaneous and ulnar nerves, splitting of the nerve, penetration of the nerve by other vessels such as brachial artery, variations with the areas of innervation of the nerve and also with the number roots forming this nerve. This study reported the formation of the median nerve at an unusually low level in the arm. This unusual level of formation was compared with standard course of this nerve as described in the anatomy  literature and atlases.
