The '''medial brachial cutaneous nerve''' ('''lesser internal cutaneous nerve'''; '''nerve of Wrisberg''', '''medial cutaneous nerve of arm''') is distributed to the skin on the medial brachial side of the arm.
It is the smallest branch of the [[brachial plexus]], and arising from the [[medial cord]] receives its fibers from the eighth cervical and first thoracic nerves. It passes through the [[axilla]], at first lying behind, and then medial to the [[axillary vein]], and communicates with the [[intercostobrachial nerve]].
It descends along the medial side of the [[brachial artery]] to the middle of the arm, where it pierces the [[deep fascia]], and is distributed to the skin of the back of the lower third of the [[arm]], extending as far as the [[Elbow-joint|elbow]], where some filaments are lost in the skin in front of the medial epicondyle, and others over the [[olecranon]].
It communicates with the ulnar branch of the [[medial antebrachial cutaneous nerve]].
