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]]. ==See also== * [[Lateral brachial cutaneous nerve]] * [[Posterior brachial cutaneous nerve]] ==Additional images== <gallery> Image:Brachial plexus.svg|Brachial plexus Image:Gray811and813.PNG|Cutaneous nerves of right upper extremity. </gallery> ==External links== * {{SUNYAnatomyFigs|06|03|04}} * {{EatonHand|ner|017}} * {{KansasHandKinesiology|nerves/medialcutan.htm}} {{Gray's}} {{Brachial plexus}} {{neuroscience-stub}} [[de:Nervus cutaneus brachii medialis]]
