Median nerve

Other Terms: Nervus medianus, Nerf médian

Description

The median nerve of the brachial plexus is the most superficial of the three chief nerves of the arm. It is formed at the lateral side, or in front of the third portion of the axillary artery. It is generally beneath the pectoralis minor muscle, by the Y-shaped union of its lateral and medial heads. The lateral head arises, with the musculocutaneous, from the lateral cord. The medial head arises with the ulnar, from the medial cord. It crosses in front of the third portion of the axillary artery. This nerve is the one most frequently injured in wounds of the axilla.
