A branch ascends between the long and lateral heads of the [[triceps brachii]] to anastomose with the [[posterior humeral circumflex artery]]; the [[medial collateral artery]], a branch, descends in the middle head of the triceps brachii and assists in forming the anastomosis above the olecranon; and, lastly, a [[radial collateral artery]] runs down behind the [[lateral intermuscular septum]] to the back of the lateral epicondyle of the humerus, where it anastomoses with the [[interosseous recurrent]] and the [[inferior ulnar collateral]] arteries. ==Additional images== <gallery> Image:Gray525.png|The brachial artery.
