Palmar digital veins

Palmar Digital Veins are veins located in the hand. They are responsible for draining blood from the fingers and palm of the hand, returning it to the heart. The term "palmar" refers to the palm of the hand, while "digital" refers to the fingers.

Etymology

The term "palmar" is derived from the Latin word "palma", which means palm. The term "digital" comes from the Latin word "digitus", which means finger.

Anatomy

The palmar digital veins are located in the subcutaneous tissue of the hand. They are paired veins, meaning there are two for each finger. These veins drain the palmar side of the fingers and the distal part of the palm. They join to form the superficial palmar venous arch, which drains into the ulnar vein and radial vein.

Function

The primary function of the palmar digital veins is to return deoxygenated blood from the fingers and palm of the hand back to the heart. This is part of the body's venous return system, which is crucial for maintaining blood circulation and overall health.
