Intracellular muscle action potentials, the corresponding to them extracellular action potentials recorded at short and long radial distances, extraterritorial motor unit potentials, evoked muscle potentials (M-, H- and T-potentials) and averaged potentials of the summated electromyogram were studied experimentally and compared with the calculated potentials. The similarity in the shape of the different muscle potentials and some second-rate differences were explained taking into account the point of recording, the different degree of desynchronization of the summated potentials and some other factors.
