The order of events in action potential generation
The neurotransmitter from the presynaptic cell binds to a ligand-gated ion channel on the postsynaptic cell and channel opens to (Na+)
A subthreshold depolarization response is generated opening some voltage-gated Na+ channels (gradient potential)
The threshold is reached activating (opening) all voltage-gated Na+ channels allowing Na+ influx (-55 mV)
(gradient potential)
An all-or - non-action potential is generated
The membrane reaches the peak voltage in which Na+ channels close. (action potential)
Voltage-gated K+ channels open (+30 mV potassium efflux)
Repolarization of cell membrane occurs (as a result of the previous step)
Hyperpolarization (more negative than -70 mV)
Potassium channels close and sodium-potassium pump takes over restabilizing the resting membrane potential (RMP) to -70 mV
