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 ...

2023年10月30日 · The lateral pectoral nerve (C5, C6, C7) typically arises as the most proximal branch of the lateral cord of the brachial plexus, immediately above or deep to the clavicle. From its origin, the nerve runs anteriorly across the axillary artery and …

2023年4月5日 · The lateral pectoral nerve, also known as the lateral anterior thoracic nerve, arises from the lateral cord of the brachial plexus and supplies the pectoralis major and pectoralis minor muscles.

2023年9月18日 · The lateral pectoral nerve is a motor nerve arising from the lateral cord of the brachial plexus. It supplies motor innervation to the pectoralis major and contributes to the innervation of pectoralis minor.

The lateral pectoral nerve is a motor nerve that supplies the pectoralis major muscle. Additionally, the lateral pectoral nerve innervates the pectoralis minor muscle via the ansa pectoralis.

The lateral pectoral nerve arises from the fifth through to the seventh cervical nerves (C5–C7) and is the larger of the two pectoral nerves. It arises from the lateral cord or from the anterior divisions of the upper and middle trunks.

2025年1月20日 · The lateral pectoral nerve is a peripheral nerve that arises from the lateral cord of the brachial plexus, typically from the C5, C6, and C7 nerve roots. It is primarily involved in the motor innervation of the pectoral muscles, particularly the pectoralis major.

2022年1月24日 · Both pectoral muscles have dual nerve supply from lateral and medial pectoral nerves. Upper clavicular part of PM muscle is supplied by LPN with a root value of C5, C6, and C7. The lower sternocostal part is supplied by medial pectoral nerve (C8 and T1).

The lateral pectoral nerve (lateral anterior thoracic; fasciculus lateralis) the larger of the two, 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 ...

In the other 38% of patients, the medial pectoral nerve exits around the lateral aspect of the pectoralis minor muscle. The lateral pectoral nerve courses on the undersurface of the pectoralis major muscle, innervating the proximal one third or more of the muscle.
