Significance of resting membrane potential

WebFeb 1, 2006 · The resting membrane potential in skeletal muscle cells is similar to that in neurons, i.e. −70 to −90 mV. Unlike nerve cells, where the resting membrane potential is predominantly a result of K + permeability, skeletal muscle cell resting membrane potential receives a significant contribution from Cl − conductance. 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.
