This diagram is especially intended for the electromyographer. It can be used as a learning tool for the beginner, or as a one stop reference for the experienced EMG'er. At first glance it may seem busy, but it is an attempt to show roots, cords, and nerves in one diagram. I am glad to take comments, positive or negative, sent to ps-plexus AT masny.dk .
