Introduction - Neuronal Action Potential

WebThe difference between the membrane potential and the equilibrium potential (-142 mV) represents the net electrochemical force driving Na + into the cell at resting membrane potential. At rest, however, the permeability of the membrane to Na + is very low so that only a small amount Na + leaks into the cell. Web30 jun. 2024 · Membrane potential: The (a) resting membrane potential is a result of different concentrations of Na+ and K+ ions inside and outside the cell. In neurons, potassium ions (K+) are maintained at high concentrations within the cell, while sodium ions (Na+) are maintained at high concentrations outside of the cell.
