Question

Quizplus · Accepted Answer

Synaptic vesicles are small, spherical structures found within the axon terminal of a neuron, also called the presynaptic neuron. These vesicles contain neurotransmitters which are released into the synaptic cleft (the small space between the presynaptic neuron and the postsynaptic neuron) when an action potential reaches the axon terminal. The “buttons” (also called synaptic end bulbs) are the axon terminals that contain the synaptic vesicles and are responsible for releasing the neurotransmitters. Therefore, choice E is the correct answer.
