It originates from the axillary artery and follows the lower border of the Pectoralis minor muscle to the side of the chest, supplies the Serratus anterior muscle and the Pectoralis major muscle, and sends branches across the axilla to the axillary lymph nodes and Subscapularis muscle.
In the female it supplies an external mammary branch which turns round the free edge of the Pectoralis major and supplies the breasts.
