Dorsal venous arch of the hand. It is a set of connections of veins formed by the union of the dorsal metacarpal veins lying in subcutaneous tissues above the metacarpal bones. It drains into the cephalic and basilic veins but most of the blood from the entire hand drains into the arch of the hand.

The dorsal venous arch of the foot works complimentarily to arteries in the region, like the arcuate artery of the foot, which is also called the metatarsal artery. Unlike veins, these arterial vessels deliver oxygenated blood from the lungs and heart, which allows for proper functioning of the foot’s muscles, tendons, and ligaments.

What is the function of the arch?
The arch assists in draining oxygen-depleted blood from the foot. Also, it receives blood from the dorsal metatarsal veins, which drains the foot’s metatarsal region (the area leading to the toe bones) and drains the dorsal digital veins servicing the toes.

What is the dorsal vein?
The dorsal venous arch of the foot is a superficial vein that connects the small saphenous vein and the great saphenous vein. Anatomically, it is defined by where the dorsal veins of the first and fifth digit, respectively, meet the great saphenous vein and small saphenous vein.
Where is the dorsal venous arch?
The dorsal venous arch lies at the distal portions of the metatarsal bones. There are medial and lateral marginal veins, which drain both of the dorsal and plantar aspects of the particular sides within the dorsal venous arch alongside the foot.
Which arch of the foot works complimentary towards arteries in the area?
The dorsal venous arch of the foot works complimentary towards arteries in the area, similar to the arcuate artery of the foot, which is also referred to as the metatarsal artery.
How many dorsal digital veins are there?
Superficial venous drainage is primarily performed by the great (long) as well as small (short) saphenous veins. 10 dorsal digital veins originate through sides of the toes. Surrounding 8 veins merge at the web of the toes creating 4 dorsal metatarsal veins.
What is the function of the arch?
Functions. The arch helps in draining oxygen-depleted blood through the foot. Also, it gets blood via the dorsal metatarsal veins, which drains the foot’s metatarsal area and also drains the dorsal digital veins supplying the toes.

Small saphenous vein: drains blood via the lateral dorsal venous arch along with posterior leg (calf) within the popliteal vein posterior towards the knee. Great saphenous vein: drains blood via the medial dorsal venous arch, leg, as well as thigh within the femoral vein just inferior towards the inguinal ligament.
Where does the blood flow in the arch?
Consequently, the blood flows within numerous other vessels in the venous system as it goes upwards to the leg and back towards the lungs along with the heart.
Does the pressure on the palm at the time of grasping obstruct the venous circulation of the palm
The pressure on the palm at the time of grasping does not obstruct the venous circulation of the palm, but instead it facilitates the restoration because venous blood via the palm is drained inside dorsal venous arch.
