WebbBut: When an action potential occurs, only a tiny, tiny amount of ions (<0.001%) need to move across the membrane to change the membrane potential. This is because membrane potential changes are not … The cardiac action potential differs from the neuronal action potential by having an extended plateau, in which the membrane is held at a high voltage for a few hundred milliseconds prior to being repolarized by the potassium current as usual. This plateau is due to the action of slower calcium channels opening and holding the membrane voltage near their equilibrium potential even after the s… the organ loft salt lake city
