ESSAY: SYNAPTIC TRANSMISSION AT A CHEMICAL SYNAPSE Explаin the trаnsmissiоn оf аn excitatоry signal across a chemical synapse between two neurons.  A step-by-step explanation (list format) is acceptable, but each step should be explained logically, with sufficient detail, and in your own words. Begin your explanation with an action potential occurring in the synaptic terminal of the pre-synaptic neuron.  Describe each event involved in causing an excitatory signal to be transmitted from the pre-synaptic neuron to the post-synaptic neuron.    Conclude when a new action potential has been generated in the postsynaptic neuron.  Also include a brief discussion of what happens to the excess/used neurotransmitter.
