What is a synapse?
the site of transmission of electric nerve impulses between two nerve cells (neurons)

What happens to a neurotransmitter once a nerve impulse has been generated in the next neurone?
the neurotransmitter is reabsorbed back into the presynaptic neuron and restored inside a vesicle ready to be used again. For example, noradrenaline
