CEPHALIC VEIN Both of which drain into brachial vein -> subclavian vein -brachiocephalic -Superior vena cava SPECIAL NERVES: 1.
Superficial veins DEEP VENOUS BLOOD FLOW Palmer metacarpal ->deep palmer veins->Radial and ulnar veins-Brachial vein->Axillary vein-subclavian->brachiocephalic SUPERFICIAL VEINS 1. Resource Settings - PLAB1-PLAB2 NOTES - Online Test of 9 2. On the left side direct from the aorta branches off common carotid artery and subclavian artery. On the right side: Aorta-brachiocephalic truncus-subclavian artery -> Axillary artery -> Brachial artery-> radial and ulnar artery-> which form the palmer arch-> digital arteries NB: The brachiocephalis truncus gives branch to common carotid artery and the subclavin artery gives branch to vertebral artery 2.
