The anterior ulnar recurrent artery is a small blood vessel located in the forearm. The vessel emerges just below the joint of the elbow and between two muscles in the forearm. These muscles are known as the brachialis and pronator teres. The artery travels slightly past the elbow joint. The anterior ulnar recurrent artery is an extension of the ulnar artery. It runs alongside the posterior ulnar artery for a short distance until their paths diverge at the joint of the elbow. The anterior ulnar artery travels straight up the front of the arm. The posterior branch curves around the elbow joint to run up the backside of the upper arm. The anterior blood vessel supplies a group of small branches that directs blood to various muscles in the arm. The anterior ulnar recurrent artery is also responsible for delivering blood flow to the middle of the elbow and the flexor region of the forearm.
