Medial cutaneous nerve of arm
Other Terms: Medial brachial cutaneous nerve, Nerve of Wrisberg, Nervus cutaneus brachii medialis, Nerf cutané médial du bras
The medial cutaneous nerve of the arm, the smallest branch of the brachial plexus, arises from the medial cord. It passes behind and along the medial side of the axillary vein, where it is joined by the intercostobrachial nerve, which is the lateral cutaneous branch of the second intercostal nerve. The medial cutaneous nerve of the arm is separated from the ulnar nerve and from the third portion of the axillary artery by the axillary vein. It supplies the skin of the medial side of the brachium.
