'''Ulnar Collateral Artery'''

[[File:Gray530.png|thumb|right|200px|Ulnar collateral artery (labeled as ulnar recurrent) and its branches.]]
The '''Ulnar Collateral Artery''' is a branch of the [[brachial artery]] in the [[upper limb]]. It is responsible for supplying blood to the medial aspect of the [[forearm]] and the [[hand]].

==Anatomy==
The ulnar collateral artery originates from the brachial artery in the [[cubital fossa]]. It then divides into two branches: the anterior and posterior ulnar recurrent arteries. These arteries anastomose with the [[ulnar artery]] to provide collateral circulation to the forearm and hand.

===Anterior Ulnar Recurrent Artery===
The anterior ulnar recurrent artery arises from the ulnar collateral artery and ascends anteriorly in the forearm. It anastomoses with the ulnar artery in the region of the [[elbow]].

===Posterior Ulnar Recurrent Artery===
The posterior ulnar recurrent artery also arises from the ulnar collateral artery but ascends posteriorly in the forearm. It anastomoses with the ulnar artery near the elbow.

==Clinical Significance==
The ulnar collateral artery is an important vessel in the upper limb. It provides collateral circulation, which is crucial in situations where the main arterial supply (via the ulnar artery) is compromised. Knowledge of its anatomy is important in surgical procedures involving the upper limb.
