The Following Are the Steps Involved in Transmission at a Cholinergic

Multiple Choice

The following are the steps involved in transmission at a cholinergic synapse. 1.Chemically-gated sodium channels on the postsynaptic membrane are activated.
2) Calcium ions enter the synaptic terminal.
3) Acetylcholinesterase hydrolyzes acetylcholine.
4) An action potential depolarizes the synaptic terminal at the presynaptic membrane.
5) The synaptic terminal reabsorbs choline.
6) Acetylcholine is released from storage vesicles by exocytosis.
7) Acetylcholine binds to receptors on the postsynaptic membrane.
8) Calcium ions are removed from the cytoplasm of the synaptic terminal.
