Neural Control And Coordination Question 41

Question: The amount of neurotransmitter released from presynaptic cell is a function of:

Options:

A) The voltage of the individual action potential in the presynaptic neuron.

B) The frequency of arriving action potentials is the presynaptic neuron.

C) Whether the action potential is excitatory or inhibitory.

D) The receptors in the postsynaptic cell.

Show Answer

Answer:

Correct Answer: B

Solution:

[b] Neurotransmitter is released from the presynaptic cell when an action potential reaches the synapse.

Increase in the frequency of arriving action potentials in the presynaptic neuron will increase the release ofneurotransmitter into the synapse.
