Lateral Pectoral Nerve

Lateral Pectoral Nerve

Key Points:
• Innervates solely the pectoralis major (clavicular head) muscle.
• Originates from roots C5, C6, C7.
EXAMINATION
Physical examination of the lateral pectoral nerve includes the motor examination of the pectoralis major muscle. The lateral pectoral nerve primarily innervates the clavicular head of the pectoralis major and could provide a small contribution to the sternocostal head.
