Question

Quizplus · Accepted Answer

The release of neurotransmitters into the synaptic cleft is triggered by the arrival of an action potential at the terminal buttons (or axon terminals) of the presynaptic neuron. This causes the vesicles containing neurotransmitters to fuse with the presynaptic membrane and release their contents into the synaptic cleft.
