The lateral pectoral nerve (also known as the lateral anterior thoracic nerve) arises from the lateral cord of the brachial plexus, [1] [2] and through it from the C5-7. [1] [2] It passes across the axillary artery and vein, [3] pierces the clavipectoral (coracoclavicular) fascia, and enters the deep surface of the pectoralis major to innervate ...

Its name comes from it being lateral to the axillary artery as it passes through the axilla. The other cords of the brachial plexus are the posterior cord and medial cord. The lateral cord gives rise to the following nerves from proximal to distal: lateral pectoral nerve (C5-C7) musculocutaneous nerve (C5-C7)
The pectoralis major receives dual motor innervation by the medial pectoral nerve and the lateral pectoral nerve, also known as the lateral anterior thoracic nerve. The sternal head receives innervation from the C7, C8 and T1 nerve roots, via the lower trunk of the brachial plexus and the medial pectoral nerve. The clavicular head receives ...

The brachial plexus is a network of nerves (nerve plexus) formed by the anterior rami of the lower four cervical nerves and first thoracic nerve (C5, C6, C7, C8, and T1).This plexus extends from the spinal cord, through the cervicoaxillary canal in the neck, over the first rib, and into the armpit, it supplies afferent and efferent nerve fibers to the chest, shoulder, arm, forearm, and hand.
Axillary nerve (blue). Also Superior lateral cutaneous nerve of arm. Inferior lateral cutaneous nerve of arm - Near blue "axillary" area, but actually branches from radial nerve. Most modern sources distinguish the superior and inferior, but some still include a single "lateral brachial cutaneous nerve". ) Intercostobrachial nerve (brown)
