Anatomy
Course
Branches from the brachial artery about a third of the way along the humerus. It travels along the medial head of the triceps towards the elbow joint, where it anastomoses with the posterior ulnar recurrent artery.
Supply
Contributes to the blood supply of the medial aspect of the arm and to the elbow joint via its branches and its contribution to the anastomosis.
The radial collateral artery contributes to the blood supply of the lateral aspect of the arm and to the elbow joint via its branches and its contribution to the anastomosis.
