Does mrpurin come to the threads? To clarify the "??"s on your studies, the muscles you coloured in orange are the brachioradialis and the extensor carpi radialis longus (the brachio on top and the ECRL below it), and the red muscle group are the extensors, yes!
And a small naming thing too, the blue muscle on the first drawing isn't the flexor carpi *radialis*, but actually the flexor capri *ulnaris*. The ulna goes to the pinky and the radius goes to the thumb, so a muscle will generally be named ulnaris/radialis based on which side of the arm it's on. Hope that helps
