Quizplus · Accepted Answer

The event required to start the process leading to the release of neurotransmitter from an axon terminal is the action potential. When an action potential reaches the axon terminal, it triggers the opening of voltage-gated calcium channels, allowing calcium to enter the terminal and initiate the release of neurotransmitters into the synaptic cleft.
