C) Muscle membrane action potential and force contraction.
 electrodes and a transducer are used to measure the change in action potential or transmembrane potential in a single cell during spontaneous activity. Simultaneous intracellular and extracellular electrical recordings and isometric force can be measureed to show the muscular activity.
