In which order neural signals travel along a neuron?

Neural signals travel along a neuron in the following order: first, an electrical impulse called an action potential is generated at the axon hillock after the neuron receives sufficient stimulation. This impulse then travels down the axon, where it is propagated by the opening and closing of ion channels. Upon reaching the axon terminals, the signal triggers the release of neurotransmitters into the synaptic cleft, allowing communication with neighboring neurons.
