What happens at the synapse between two neurons?

(N/A) synapse is a microscopic gap between the axon terminal of one neuron and the dendrite of the next neuron.
It functions as a one-way valve,ensuring that nerve impulses travel in only one direction.
This unidirectional transmission occurs because chemical messengers (neurotransmitters) are stored only in the axon terminals of the presynaptic neuron.
When an electrical impulse reaches the axon terminal,these chemicals are released into the synaptic cleft.
They diffuse across the gap and bind to specific receptors on the dendrite of the postsynaptic neuron,where they trigger a new electrical impulse.
