WebAt rest, there are relatively more sodium ions outside the neuron and more potassium ions inside that neuron. Action Potential The resting potential tells about what happens when a neuron is at rest. An action potential occurs when a neuron sends information down an axon, away from the cell body. WebResting Potential Sodium and potassium ions move from areas of high concentration to areas of low concentration, based on permeability. Because resting cell membranes are more permeable to potassium ions than sodium ions, the potassium ions diffuse out of cells more rapidly than sodium ions diffuse.

Web28 jun. 2015 · If the Donnan equilibrium were to become fully established, the increase in intracellular ions would cause cells to swell due to the osmotic influx of water. At a Donnan equilibrium, the resting membrane potential would be only about -20 mV. This potential would exist even if the membrane permeability for all ions was the same.
