Superior Thoracic Artery

The superior thoracic artery is a small artery which arises from the anterior surface of the first part of the axillary artery. It carries oxygenated blood and supplies the upper regions of the medial and anterior axillary walls. The superior thoracic artery superior travels foward and diagonally to the side of the chest, between the pectoralis minor and the pectoralis major muscles, anastomosing with the internal mammary and intercostal arteries.
