Chemical synapse neurotransmission. Impulse-stimulated synaptic vesicles in the axon synaptic terminal release neurotransmitter molecules, which cross the synaptic cleft and attachto receptors in the postsynaptic dendritic spine. If a thre shold level is reached, the impulse is sent on. Reuptake pumps absorb neurotransmitter molecules for vesicle reuse.
