It passes behind the first part of the [[axillary artery]], curves forward between the axillary artery and vein, and unites in front of the artery with a filament from the [[Lateral pectoral nerve|lateral nerve]]. It then enters the deep surface of the [[Pectoralis minor]], where it divides into a number of branches, which supply the muscle. Two or three branches pierce the muscle and end in the [[Pectoralis major]]. ==See also== * [[Lateral pectoral nerve]] ==Additional images== <gallery> Image:Brachial plexus.svg|Brachial plexus </gallery> ==External links== * {{SUNYAnatomyLabs|05|st|05|11}} * {{EatonHand|ner|016}} * {{LoyolaMedEd|GrossAnatomy/dissector/practical/ue/ue15.html}} * {{eMedicineDictionary|Medial+pectoral+nerve}} {{Gray's}} {{neuroscience-stub}} {{Brachial plexus}} [[Category:Nervous system]] [[sv:Nervus pectoralis medialis]]
