WebThis is called the resting potential. This potential difference when there are no impulses is usually about -70mV (ie. the inside of the axon has an electrical potential about 70mV lower than the outside) Two factors contribute to establishing and maintaining the resting potential: The active transport of sodium ions and potassium ions. Webresting membrane potential. Later, we will talk about the membrane when it utilizes its potential, and we will call it the action potential. The resting membrane potential is due to specific ions, mainly potassium, and their tendency to diffuse down concentration gradients until opposed by electrical forces of opposite, but similar, magnitude.
