WebFeb 5, 2024 · Action potential is the membrane potential when the transmission of a signal occurs along the axon. The action potential is normally generated due to a depolarizing current. Due to the opening of K + ion channels for longer periods of time causes the voltage of the action potential to go past -70 mV. WebAction Potential: An action potential is a brief electrical signal that travels along the axon of a neuron, allowing for the rapid transmission of information between neurons. It is initiated by a depolarization wave, which causes a temporary reversal in the electrical potential across the neuronal membrane.
