The '''arteria profunda brachii''' (also known as '''deep artery of the arm''') is a large vessel which arises from the [[medial]] and back part of the [[brachial]], just below the lower border of the [[Teres major]].
==Course==
It follows closely the [[radial nerve]], running at first backward between the medial and lateral heads of the [[triceps brachii]], then along the groove for the [[radial nerve]], where it is covered by the lateral head of the triceps brachii, to the lateral side of the arm; there it pierces the [[lateral intermuscular septum]], and, descending between the [[brachioradialis]] and the [[brachialis]] to the front of the [[lateral epicondyle]] of the [[humerus]], ends by anastomosing with the [[radial recurrent artery]].
==Branches and anastomoses==
It gives branches to the [[deltoid muscle]] (which, however, primarily is supplied by the [[posterior circumflex humeral artery]]) and to the muscles between which it lies; it supplies an occasional [[nutrient artery]] which enters the [[humerus]] behind the deltoid tuberosity.
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.
