Question

Quizplus · Accepted Answer

Neurotransmitters are released from the synaptic terminals/knobs which are the small enlargements at the end of the axon terminals. These knob-like structures contain vesicles filled with neurotransmitters that are released into the synaptic cleft, where they bind with receptors on the postsynaptic membrane. The other options (dendrites, collaterals, hillock) are not involved in the actual release of neurotransmitters. The synapse refers to the gap between the presynaptic and postsynaptic membranes where the neurotransmitters are released and received.
