Quizplus · Accepted Answer

Propagation of an action potential to the axon terminal triggers the opening of calcium voltage-gated channels. This allows calcium ions to enter the terminal, leading to the release of neurotransmitters into the synaptic cleft. Sodium and potassium voltage-gated channels are involved in generating and propagating the action potential along the axon, while acetylcholine and dopamine are neurotransmitters that are released into the synaptic cleft.
