The right subclavian artery arises from the brachiocephalic artery, behind the right sternoclavicular joint. It passes upward and laterally as a gentle curve behind the scalenus anterior muscle, and at the outer border of the first rib becomes continuous with the axillary arch. The left subclavian artery arises from the arch of the aorta, behind the left common carotid artery. It ascends to the root of the neck and then arches laterally in a manner similar to that of the right subclavian artery.
