Just to make sure I have this correctly:
1. Acetylcholine binds to a postsynaptic membrane
2. Sodium ion channels open up, allowing influx of Na+ ions into the cell
3. In response, K+ ions exit the cell
4. Increased charge (charge that becomes less negative) in the cell due to all the Na+ ions is called depolarization
5. Once depolarization reaches an absolute threshold, an action potential occurs
6. Once action potential is completed, a Na/K pump uses ATP to move Na+ back out of the cell...
Sequence of events of action potential?
