Nerve: Lateral pectoral nerve
Nerves of the left upper extremity. (Lateral anterior thoracic visible in upper right.)
Latin	n. pectoralis lateralis
Gray's	subject #210 933
Innervates	pectoralis major
From	lateral cord

The lateral pectoral nerve (lateral anterior thoracic) arises from the lateral cord of the brachial plexus, and through it from the fifth, sixth, and seventh cervical nerves.

It passes across the axillary artery and vein, pierces the coracoclavicular fascia, and is distributed to the deep surface of the Pectoralis major.

It sends a filament to join the medial anterior thoracic and form with it a loop in front of the first part of the axillary artery.
