Cholinergic Syn

Cholinergic Synapses

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
