It passes backward between the oblique cord and the upper border of the interosseous membrane. It appears between the contiguous borders of the supinator and the abductor pollicis longus, and runs down the back of the forearm between the superficial and deep layers of muscles, to both of which it distributes branches.
It gives off, near its origin, the interosseous recurrent artery, which ascends to the interval between the lateral epicondyle and olecranon, on or through the fibers of the Supinator, but beneath the anconeus, and anastomoses with the radial collateral branch of the profunda brachii, the posterior ulnar recurrent and the inferior ulnar collateral.
