What is an action potential

Question

Quizplus · Accepted Answer

An action potential is an electrical signal that travels along the axon of a neuron. It is an important process in the communication between neurons. The action potential is generated when the neuron reaches a certain threshold of depolarization, causing an influx of positive ions into the cell, which leads to a rapid change in electrical potential that travels along the axon. This signal triggers the release of neurotransmitters, which then activate or inhibit the electrical activity of neighboring neurons.
