Veins Finger Palmar

The palmar digital veins, or palmar digital veins, are important vessels that provide blood supply to the hand and palm. They originate from the deep veins of the wrist and pass through the palmar surface of the hand, branching into many small venous trunks.

The digital palmar veins play a key role in the blood flow of the hand. When a person makes a fist, venous blood must pass through this complex capillary organ to reach the large veins on the back of the hand and wrist. This can be difficult due to pinched or blocked blood vessels, which can lead to swelling and pain in the arm.

In addition, the palmar digital veins help maintain body temperature in the hand and combat stress in the hand when working in hot conditions. Their tone may decrease due to prolonged immobile position of the hand or increased physical stress on the hand.

One of the main reasons for impaired blood flow in this organ is weight gain. The physical load on the upper limb increases as a result of carrying additional loads. This increases the pressure in the arteries supplying the vessels of the fingers. Because of this, blood may not flow to organs and tissues, but is retained in small fingers.

The palmar digital veins (v. digitalis palmaris, pna; v. digitalis palmaticus, BNA) are branches of the palmar arch of the ulnar vein. They start from the first bone canal of the wrist and pass deep into the palmar aponeurosis, where they anastomose with the venous formations of the fingers (sometimes forming a common digital vein), and then accompany the flexor tendons of the fingers and, approaching the root, flow into the superficial palmar artery. In the carpal canal, the digital palmar vein is divided into terminal branches - the capillary networks of the palms. Digital veins can be superficial or deep. Tributaries are present only at the deep digital vein and they are mainly represented by the veins of the triflexor digitorum and the veins of the hand.
