Ulnar veins

From WikiMD's Wellness Encyclopedia

Ulnar veins are veins that accompany the Ulnar artery in the forearm. They are generally larger than the radial veins. They begin at the hand and end at the brachial vein.

Etymology[edit | edit source]

The term "ulnar" is derived from the Latin word "ulna," which means "elbow." This is because the ulnar veins are located near the ulna bone in the forearm.

Anatomy[edit | edit source]

The ulnar veins begin at the level of the hand where they drain blood from the superficial palmar arch. They ascend along the ulna bone, accompanying the ulnar artery. They are generally larger than the radial veins. At the level of the elbow, the ulnar veins merge with the radial veins to form the brachial vein.

Function[edit | edit source]

The primary function of the ulnar veins is to carry deoxygenated blood from the hand and forearm back to the heart. They work in conjunction with the radial veins to accomplish this task.

Clinical significance[edit | edit source]

The ulnar veins, like other veins in the body, can be affected by various medical conditions. These include deep vein thrombosis, varicose veins, and phlebitis. In some cases, the ulnar veins may be used for venipuncture, the process of drawing blood for diagnostic purposes.
