WebBut when it reaches the action potential, that opens the sodium channels wide, letting sodium ions flood in temporarily. When the potential reaches the second threshold, the sodium channels close again (and the potassium channels open wide, rapidly restoring the resting potential), so sodium is once again blocked from reentering the cell. WebThe (a) resting membrane potential is a result of different concentrations of Na + and K + ions inside and outside the cell. A nerve impulse causes Na + to enter the cell, resulting in (b) depolarization. At the peak action …

Web$\begingroup$ If you see a normal AP curve, you would be able to appreciate that the membrane potential is generally brought back - which is around -70mV. So the potential … WebAn action potential is a transient, electrical signal, which is caused by a rapid change in resting membrane potential (-70 mV). This occurs when the threshold potential (-55 mV) is reached, this causes a rapid opening in the voltage-gated sodium channels leading to an influx of sodium ions into the cell. The threshold potential also causes a ...
