Superior thoracic artery
The superior thoracic artery (highest thoracic artery) is a small artery[1] located near the armpit. It usually arises from (the first division of) the axillary artery, but may sometimes instead arise 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]
