The superior thoracic artery (highest thoracic artery) is a small artery[1] located near the armpit.[citation needed] It usually originates from (the first division of) the axillary artery, but can instead originate from the thoracoacromial artery (itself a branch of the second division of the axillary artery). It supplies the pectoralis minor and major muscles, and the chest wall.[1]
