Completar Frases Voltage gated channels and action potentialsVersión en línea Fill in the blanks por Jessica 1 An action potential is a rapid , change in membrane potential that occurs when a neuron reaches , typically around ? 55 mV . This process depends on the coordinated activity of - gated sodium and potassium channels . 2 When threshold is reached , - gated channels open rapidly . ions diffuse into the neuron their gradient , causing rapid of the membrane . This creates a feedback effect , where further depolarisation opens sodium channels , producing the steep rising phase of the action potential . 3 At the peak of the action potential , - gated channels become , preventing further sodium entry . At the same time , voltage - gated channels , which open more , begin to open . Potassium ions diffuse the neuron , leading to of the membrane . 4 Potassium channels remain slightly longer than necessary , causing , where the membrane potential becomes more than the resting level . During this time , channels reset from the inactivated to the state . The inactivation of channels produces the refractory period , while continued efflux contributes to the refractory period . 5 - gated channels ensure that action potentials are - or - events and propagate along the axon loss of amplitude . Following the action potential , normal ion distributions are gradually restored by the ? potassium pump .
