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.
Arteries of lower limbs. The artery that supplies the greater part of the lower extremity is the direct continuation of the external iliac. It runs as a single trunk from the inguinal ligament to the lower border of the popliteal fossa, where it divides into 2 branches, the anterior and posterior tibial arteries.
