††† Law polar actions DC: the buy Priligy online closure of the current excitation occurs at the cathode, and when open - under the anode. Passage of xenical buy a direct electric current through the nerve or muscle fiber causes a change in membrane potential. Thus, in the application area of the cathode the positive potential on the outer side of the membrane is reduced, there is depolarization, which rapidly reaches a critical level and cause arousal. In the same application of the anode a positive potential on the outer side membranyvozrastaet occurs hyperpolarization of the membrane and excitation occurs. But at the same time under the anode critical level of depolarization shifts to the level of the resting potential. Therefore, open circuit voltage across the membrane hyperpolarization disappears, and the resting potential, returning to the initial value, the offset reaches a critical level and there is excitement.
