WebApr 10, 2024 · The ventricular action potential is generally split into 5 phases ( phases 0-4 ). Rather confusingly, phase 4 is the baseline that the membrane potential begins and ends at. Like any action potential, each phase is driven by the opening and closing of a variety of specific ion channels. This is because opening an ion channel will push the ... WebThis movement of sodium ions and potassium ions across the membrane causing the wave form of the action potential starts here at the trigger zone at the axon initial segment, but then rapidly spreads in waves down the axon. First, there's the wave of depolarization from opening up the voltage gated sodium channels.

WebAction potentials are considered an “all-or nothing” event, in that, once the threshold potential is reached, the neuron always completely depolarizes. Once depolarization is complete, the cell must now “reset” its membrane voltage back to the resting potential. To accomplish this, the Na + channels close and cannot be opened.
