Volar arteries

Volar arteries

The volar arteries are a group of arteries located in the forearm and hand. These arteries are primarily responsible for supplying blood to the palmar aspect of the hand and the fingers. The term "volar" is synonymous with "palmar," referring to the palm side of the hand.

Anatomy

The volar arteries include several important branches:

• Radial artery: This artery travels down the lateral aspect of the forearm and contributes to the blood supply of the hand. It gives rise to the superficial palmar branch and the deep palmar arch.
• Ulnar artery: This artery runs along the medial side of the forearm and also plays a crucial role in hand vascularization. It forms the superficial palmar arch and gives off the common palmar digital arteries.
• Superficial palmar arch: Formed mainly by the ulnar artery, with a contribution from the radial artery, this arch supplies blood to the palm and fingers.
• Deep palmar arch: Primarily formed by the radial artery, with a contribution from the ulnar artery, this arch supplies the deep structures of the hand.

Function

The primary function of the volar arteries is to provide oxygenated blood to the muscles, tendons, ligaments, and skin of the palm and fingers. This blood supply is essential for the proper functioning and health of the hand.

Clinical Significance

Injuries or conditions affecting the volar arteries can lead to compromised blood flow to the hand, resulting in conditions such as ischemia, gangrene, or compartment syndrome. Proper diagnosis and treatment of such conditions are crucial to prevent permanent damage to the hand.
