Lateral pectoral nerve
Encyclopedia
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
.
