Anatomical terminology [edit on Wikidata] |
The superior thoracic artery (highest thoracic artery) is a small artery[1] located near the armpit.[2] 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]
Anatomy
Course and relations
It passes anteromedially along medial upper border of the pectoralis before passing between pectoralis minor and pectoralis major to reach the chest wall.[1]
Anastomoses
It forms anastomoses with the internal thoracic artery, and upper intercostal arteries.[1]
