Describe in detail the process of synaptic transmission. Start with the arrival of an action potential at a knob.  Include details regarding an IPSP and an EPSP example in the postsynaptic neuron. Also include clearing the synaptic cleft (gap). Use the back of this page as needed.  You may use drawings and words.
