Arterial supply of the upper limb. Dr Omar Bashir et al. The arterial supply of the upper limb is derived from the subclavian artery. The right subclavian artery originates from the brachiocephalic artery, which is the first branch of the aortic arch. The left subclavian artery originates directly from the aortic arch, being the third branch.
Arteries of the upper limb. Aorta. arch of aorta gives off three branches. a) brachiocephalic artery-divides into: 1) right common carotid artery-passes superiorly into neck. 2) right subclavian artery-arches laterally, deep to clavicle; to right upper limb. b) left common carotid artery-directly off arch of aorta. c) left subclavian artery-directly off arch f aorta; to left upper limb.
