Answer:
Voltage-gated membrane channels open, and Ca+2 enters the cytoplasm, increasing intracellular calcium
Explanation:
The neurotransmitters in the neurons are stored in the synaptic vesicles in the synaptic knob present at the axon terminal.
The neurotransmitters are released when the action potential reaches the axon terminal and opens up the voltage-gated calcium channels. The calcium channels allow the entry of the calcium from the synapses and this causes the release of the synaptic vesicles which fuses with the cell membrane. This fusion releases the neurotransmitter in the synapse.
