What vein drains the radial and ulnar veins?
They arise in the hand and terminate when they join the radial veins to form the brachial veins. They follow the same course as the ulnar artery….

Which vein receives blood from the superficial palmar arch?
| Superficial palmar arch | |
|---|---|
| Source | Ulnar (primarily), Superficial palmar branch of the radial artery |
| Branches | Common palmar digital |

Where does the superficial palmar arch supply blood to?
The main function of the superficial palmar arch is to provide blood supply to the phalanges, metacarpophalangeal and interphalangeal joints of digits 2-4. It does so via its three branches called the common palmar digital arteries.
What does the deep palmar venous arch drain?
The deep palmar arch is accompanied by a pair of venae comitantes which constitute the deep palmar venous arch….

Which artery is the main contributor of deep palmar arch?
radial artery
The deep palmar arch is usually primarily formed from the radial artery. The ulnar artery also contributes through an anastomosis. The deep palmar arch lies upon the bases of the metacarpal bones and on the interossei of the hand.
How many palmar arches are there?
Hand has derived its arterial supply, from two anastomotic arches, superficial and deep palmar arches which are formed between two main arteries of forearm i.e. radial, ulnar and their branches, in the palm.
How superficial palmar arch is formed?
ulnar artery
The superficial palmar arch (superficial volar arch; arcus volaris superficialis) is formed by the ulnar artery, and is usually completed by a branch from the a. volaris indicis radialis, but sometimes by the superficial volar or by a branch from the a. princeps pollicis of the radial artery.
What is great saphenous vein?
The saphenous vein (otherwise known as the great saphenous vein or GSV) is the longest in the human body. It extends from the top of the foot to the upper thigh/groin area and like all veins, problems can occur.
Where is the superficial palmar venous arch located?
Superficial palmar venous arch The superficial palmar venous arch is located in the hand, and assists in draining oxygen-depleted blood from the hand and the common palmar digital veins within the fingers. From there, blood drains through the arch and up the ulnar vein.
Where is the superficial palmar artery in the thumb?
The superficial palmar arch is located in the level of the distal boundary of the completely expanded thumb throughout the centre of the palm. Distally, the ulnar artery is medial towards the hook of the hamate bone and afterwards sways laterally over the palm, creating the superficial palmar arch that is superficial towards…
Where does the palmar arch of the hand come from?
Superficial palmar arch (Arcus palmaris superficialis) The superficial palmar arch is an anastomotic vessel found in the palmar (volar) compartment of the hand. Its main source is the ulnar artery, with a smaller contribution from the radial artery.
Where does the ulnar artery and palmar artery connect?
The ulnar artery together with ulnar nerve gets into the hand at the medial side of the wrist. The vessel is located among the palmaris brevis as well as the flexor retinaculum and also lateral to the ulnar nerve along with the pisiform bone. The arch connects with a palmar branch of the radial artery on the lateral side of the palm.
