Intercommunications between musculocutaneous nerve and median nerve deserve important interest in view of their clinical significance. In the study of 50 upper limb specimens, the various communications between the musculocutaneous and median nerve in the arm were observed carefully. The communications between the two nerves were found in 13 arms. Variations in the present study involving the median nerve and musculocutaneous nerve are important in repairs for trauma to the shoulder and the understanding of the median nerve and the musculocutaneous nerve dysfunction.
