When More Action Potentials Arrive at the Axon Terminal, How

question 127

Multiple Choice

When more action potentials arrive at the axon terminal, how is the postsynaptic cell affected?

• A) Neurotransmitter release increases, but does not change the graded potentials that follow.
• B) Neurotransmitter release does not change, thus the postsynaptic cell behaves the same way it always behaves.
• C) Neurotransmitter release increases, thereby increasing the frequency or magnitude of graded potentials in the postsynaptic cell.
• D) Neurotransmitter release does not change, but voltages applied to the postsynaptic cell increase.
