Ulnar veins
Large blood vessels of the forearm
The ulnar veins are venae comitantes of the ulnar artery. They drain the superficial venous palmar arch[dubious ].[1] They arise in the hand and terminate by uniting with the radial veins to form the brachial veins. They mostly drain the medial aspect of the forearm.[citation needed] They receive the venae comitantes of the anterior and posterior interosseous arteries near the elbow, as well as a large branch from the median cubital vein. The ulnar veins are larger than the radial veins.[1]
They follow the same course as the ulnar artery.[citation needed]
