Question

Quizplus · Accepted Answer

Synaptic vesicles store and release neurotransmitters at the presynaptic membrane. Exocytosis of vesicles occurs at the presynaptic membrane in response to an action potential, leading to the release of neurotransmitters into the synaptic cleft. The dendrites, axon hillock, nodes of Ranvier, and postsynaptic membrane all play important roles in transmitting or receiving signals but are not directly involved in the exocytosis of synaptic vesicles.
