Its origin is variable. When it arises from the brachial artery, it is given off opposite the groove of the humerus destined for the radial nerve, and descends backwards between the three portions of the triceps, accompanied by the nerve; giving branches to that muscle and to the humerus. When it reaches the posterior part of the bone, it divides into two branches, which are distributed to the triceps, supinator longus, &c.
