Metacarpal artery

Metacarpal Artery

The metacarpal artery and its branches.

The metacarpal artery is a significant part of the human anatomy, specifically the hand anatomy. It is one of the branches of the deep palmar arch, which is itself a branch of the ulnar artery. The metacarpal artery primarily supplies blood to the metacarpal bones and the associated structures in the hand.

Structure

The metacarpal artery typically branches off from the deep palmar arch. It runs along the metacarpus, giving off several smaller branches that supply the metacarpal bones, the interosseous muscles, and the skin and fascia of the hand.

Function

The primary function of the metacarpal artery is to supply blood to the metacarpal bones and the surrounding structures. This includes the interosseous muscles, which are responsible for the movement of the fingers and thumb, and the skin and fascia of the hand.

Clinical significance

Knowledge of the metacarpal artery is crucial in hand surgery, particularly in procedures involving the metacarpal bones or the deep structures of the hand. Damage to the metacarpal artery during surgery can lead to significant blood loss and potential complications.
