Synaptic Transmission

Item #10 of 15

Which of the following is(are) true about postsynaptic potentials (PSPs)?

A neurotransmitter must be released into the synaptic cleft.;

A neurotransmitter must bind or fit into a receptor site.;

A postsynaptic potential is a graded response.;

It affects the probability of a neuronal impulse based on its size and polarity.;

All of the above alternatives are correct;

CORRECT - Yes, a postsynaptic potential is dependent on the release of a neurotransmitter into the synaptic cleft that binds to a receptor site. A PSP is a graded response that affects the probability of the generation of a neuronal impulse based on its size and polarity.
