Description
Summary:Atypical connections in the formation of the brachial plexus are prevalent and have been reported in different articles. The present report describes a case of variation of the median nerve observed in the Iranian male cadaver during routine trial dissection. There are three roots for median nerve. Median nerve is formed by joining two lateral and medial cords of brachial plexus. Third root of median nerve which is carried by musculocutaneous nerve 3 cm of coracobrachialis muscle and then it is separated from musculocutaneous nerve but instead of joining median nerve, it pierces coracobrachialis muscle and outs from a place near entrance point and joins median nerve in middle arm and normally passes the rest of its passage. It is important for medical staff to be aware of this variation while planning a surgery in the region of axilla or arm, as these nerves are more susceptible to be injured during operations.
