<P> In a neuron , synaptic vesicles ( or neurotransmitter vesicles ) store various neurotransmitters that are released at the synapse . The release is regulated by a voltage - dependent calcium channel . Vesicles are essential for propagating nerve impulses between neurons and are constantly recreated by the cell . The area in the axon that holds groups of vesicles is an axon terminal or `` terminal bouton '' . Up to 130 vesicles can be released per bouton over a ten - minute period of stimulation at 0.2 Hz . In the visual cortex of the human brain , synaptic vesicles have an average diameter of 39.5 nanometers ( nm ) with a standard deviation of 5.1 nm . </P>
