What is the correct sequence of events along an axon that follows a membrane reaching threshold potential?
Oksi-84 [34.3K]

As sodium ions diffuse inward, sodium channels open.

Membrane depolarization occurs.

Potassium ions spread outward as potassium channels open.

Membrane repolarization occurs.

<h3>What happens along an axon in the right order ?</h3><h3 />

An action potential, which is a fast change in membrane potential, develops when the membrane potential of a neuron's axon hillock hits threshold. There are three steps to this shifting change in membrane potential. Depolarization occurs first, then repolarization, and then there is a brief phase of hyperpolarization.

  • A depolarizing current causes an explosion of electrical activity known as the action potential. This indicates that the resting potential shifts toward 0 mV as a result of some action (a stimulus).
