If Time can bring you down...Time can bend your knees.... What else has time been responsible for you doing? I've been thinking there's a lot of stuff I don't really want to take full responsibility for...heh heh.
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.
Brachial artery is the main arterial supply of the upper limb providing the blood supply to nearly all of its structures. It is a medium sized artery and is actually a continuation of the axillary artery from the region of the axilla into the arm.
