You overhear two men at the gym talking about their extensor muscles of the forearm. Based on what you know about the motion at joints, how would you describe the movement of these muscles?

As you can see from the picture below all the extensor muscles connect the forearm to the hand and allow you to pull and extend your wrist in various directions.
