A connecting branch between the musculocutaneous nerve and the median nerve.

We report here a connecting branch between the musculocutaneous and the median nerves in a 42 years old male cadaver. The connecting branch was 8 cm in length and 3 mm in width. One of the brachial veins and the brachial artery were located between the roots of the median nerve and the second brachial vein was present between the connecting branch and the median nerve. These kinds of variations may effect the venous return and may cause edema in the upper extremities. Additionally, variations of these nerves have an importance during operations of this region.
