Nerves and vessels of UL

Blood vessels of UL. ARTERIES Origin Course & relations Termination Branches Distribution Anastomoses if any Sites of peripheral arterial pulsations-surface landmarks Clinical correlates.

Arteries of the upper limb. Subclavian A in the root of the neck Becomes Axillary A in the axilla Becomes brachial A in the arm Divides into the cubital fossa into: R adial A: F orms the deep palmar arch in the hand Contributes to superficial palmar arch Ulnar A : Gives interosseous artery in forearm Forms the Superficial palmar arch Contributes to deep palmar arch.
