The relative concentration of sodium (Na+) and potassium (K+) in the neuron with respect to their concentration in the extracellular space is what causes the electrical potential and the differential...
The resting membrane potential difference between the inside and the outside of the cell is the result of selective permeability of the cell membrane and the active transport of ions into and out of...
The resting membrane potential is important because it maintains a 'ready state' for the cell to fire. Without the resting membrane potential there would be no driving force for ions like sodium to...
