Cholinergic Syn
Cholinergic Synapses
| Question | Answer |
|---|---|
| Action Potential arrives, depolarizes the synaptic terminal | 1 |
| Extracellular Ca2+ enters the synaptic terminal, triggers exocytosis of ACh, terminates when ca ions are removed from cytoplasm of terminal | 2 |
| ACh binds to receptors and depolarizes the postsynaptic membrane by opening chemically gated sodium channels | 3 |
| ACh is broken down into acetate and choline by AChE, they synaptic terminal reabsorbs the choline to resynthesize ACh | 4 |
