Once stimulated a single action potential
Web17. jan 2024. · Action potential is a brief reversal of membrane potential in which the membrane potential changes from -70mV to +30mV. The action potential has three main stages: depolarization, repolarization, and hyperpolarization. Depolarization is caused when positively charged sodium ions rush into a neuron with the opening of voltage-gated … WebThe action potential is said to be all-or-nothing because it occurs only for sufficiently large depolarizing stimuli, and because its form is largely independent of the stimulus for …
