The arterial supply of the hand primarily comes from the radial and ulnar arteries, which form two main arches:
โข Superficial Palmar Arch:
โข Mostly formed by the ulnar artery, sometimes completed by a branch of the radial artery.
โข Lies just under the skin and superficial fascia of the palm.
โข Gives rise to common palmar digital arteries, which further divide into proper palmar digital arteries supplying the fingers.
โข Deep Palmar Arch:
โข Formed mainly by the radial artery, often completed by the ulnar artery.
โข Lies deep to the flexor tendons.
โข Gives off palmar metacarpal arteries that anastomose with the common palmar digital arteries.

Veins of the hand are mostly superficial and communicate with deep veins. Key veins include:
โข Dorsal Venous Network:
โข Visible on the back of the hand.
โข Drains into the cephalic vein (lateral side) and basilic vein (medial side).
โข Superficial Palmar Veins:
โข Accompany the superficial arteries and help return blood from the fingers.
โข Deep Palmar Veins:
โข Follow the arteries, including the radial and ulnar arteries, and drain into the forearm veins.

โข Arteries supply oxygenated blood to support movement and sensation.
โข Veins ensure efficient blood return to maintain circulation.
โข The rich anastomoses between radial and ulnar arteries protect against ischemia if one artery is blocked.
