| Here the vessel is more superficial, lying in the groove between the flexor carpi radialis and supinator longus. |
| The intermediate and ulnar sets of muscles are supplied by branches from the deep ramus of the radial nerve after it has passed through the supinator muscle. |
| It may also join the supinator, the tendon of pronator teres, or the ulna. |
| Distally, it branches off, and attaches to the supinator crest. |
| The supinators include the supinator and biceps brachii muscles. |
| The humerus is remarkable for the great development of the supinator ridge. |
