Question

Quizplus · Accepted Answer

The binding of ACh at the neuromuscular junction results in the opening of Na⁺ channels and depolarization of the postsynaptic cell membrane.This is an example of an excitatory postsynaptic potential.In contrast,an inhibitory postsynaptic potential results in the opening of potassium and chloride ion channels and hyperpolarization of the postsynaptic cell membrane.Presynaptic facilitation and inhibition refer to the amount of neurotransmitter released into the synapse.
