| Question | Answer |
| What does the arrival of AP's at the PREsynapse cause? | Ca++ INFLUX |
| What causes the Synaptic Vesicles to rupture? | AP --> Ca++ INFLUX |
| What happens when the Synaptic Vesicles rupture? | DIFFUSION of Neurotransmitter across Synaptic Cleft --> POSTsynaptic Reactive Sites |
| What does the Neurotransmitter do? | changes Ion Permeability of POSTsynaptic membrane --> Na+ INFLUX |
| What happens during POSTsynaptic Depolarization? | Enzymic Hydrolysis & PREsynaptic reabsorption of Neurotransmitter --> Repolarization --> AP at 1st POSTsynaptic Node |
| Why do we need Repolarization? | otherwise AP's would only get through 1ce |
