The interior surface of a neuron's plasma
WebAug 24, 2024 · The nerve cell plasma membrane is extremely porous to positively charged potassium ions (K+), and the measured membrane potential of many of these nerve cells (as described above sixty to seventy-five mV) is near to that anticipated by the Nernst equation for positive potassium ions (K+). WebFigure 2. The (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 …
