Ulnar vein
Ulnar Vein
The Ulnar Vein (pronounced: UHL-nahr vayn) is a significant vein in the human body, specifically located in the forearm. It is named after the Ulna, one of the two long bones in the forearm, with which it runs parallel.
Etymology
The term "Ulnar" is derived from the Latin word "ulna," which means "elbow" or "forearm." The term "vein" comes from the Latin word "vena," which means "blood vessel."
Anatomy
The Ulnar Vein begins in the hand, where it is formed by the union of the Deep Palmar Venous Arch and the Dorsal Venous Network of Hand. It runs up the forearm, parallel to the Ulna bone, and drains into the Brachial Vein in the upper arm.
The Ulnar Vein is responsible for carrying deoxygenated blood from the forearm and hand back to the heart. It is one of the two main veins in the forearm, the other being the Radial Vein.
