The nerve leaves the medial cord of the brachial plexus where the plexus lies posterior to the axillary artery. The nerve winds around the axillary artery and vein to join a ramus of the lateral pectoral nerve anterior to the artery. It enters the posterior surface of pectoralis minor to supply it, and may pierce the muscle and/or send branches around its inferior border to supply pectoralis major.
