Neurons communicate via synaptic connections. Arrange the following events in the correct order that they occur in synapse function.
a. The neurotransmitters travel across synaptic cleft & stimulate receptors on dendrite of post-synaptic neuron.
b. An impulse reaching terminal of the presynaptic neuron stimulates the release of neurotransmitters
c. Re-uptake transporters clean up remaining neurotransmitters and store them for later use.
d. The neuroransmitters are released into the synaptic cleft.
