Potassium ions in the body
WebEffect of potassium ions on resting membrane potential In case the concentration of potassium ions on the cytoplasmic side of the membrane is 140 mmol/l and outside 4 mmol/l the Nernst potential is -94 mV. Due to a high permeability for potassium the resting potential in an alpha motor neuron is close to the Nernst potential for potassium.
