Question

Quizplus · Accepted Answer

When an action potential reaches the axon terminal, it causes voltage-gated calcium channels to open. Calcium ions then enter the axon terminal and trigger the release of neurotransmitters into the synapse, which can then bind to receptors on the next neuron and initiate an action potential.
