Dorsal metacarpal veins

Anatomy of the dorsal metacarpal veins

The dorsal metacarpal veins are a group of veins located on the dorsal aspect of the hand. These veins are responsible for draining blood from the metacarpal bones and the dorsal venous network of the hand. They play a crucial role in the venous return from the hand to the heart.

Anatomy

The dorsal metacarpal veins are situated on the back of the hand, overlying the metacarpal bones. They are part of the superficial venous system of the upper limb. These veins typically form a network that connects with the dorsal venous arch of the hand.

Connections

The dorsal metacarpal veins drain into the dorsal venous network of the hand, which is a prominent venous structure on the dorsum of the hand. This network then drains into the cephalic vein and the basilic vein, which are major superficial veins of the arm.

Function

The primary function of the dorsal metacarpal veins is to facilitate the return of deoxygenated blood from the hand back to the heart. They are part of the body's venous system, which is responsible for returning blood to the heart after it has delivered oxygen and nutrients to the tissues.

Clinical Significance

The dorsal metacarpal veins are often used for intravenous therapy and venipuncture due to their superficial location and accessibility. They are also important in the context of vascular surgery and phlebotomy.
