When Cholinergic Receptors are Stimulated

Question

When cholinergic receptors are stimulated,
A) sodium ions enter the postsynaptic neuron.
B) sodium ions leave the postsynaptic neuron.
C) chloride ions enter the postsynaptic neuron.
D) chloride ions leave the postsynaptic neuron.
E) norepinephrine deactivates acetylcholine.

Accepted Answer

When cholinergic receptors are stimulated by acetylcholine, it opens ion channels that allow positively charged sodium ions to enter the postsynaptic neuron, leading to depolarization of the membrane potential and potential generation of an action potential.
