The effect of the inhibitory neurotransmitter on the postsynaptic membrane is to a. maintain the resting potential b. hyperpolarize the postsynaptic membrane c. depolarize the postsynaptic membrane d. decrease the threshold level

Excitatory neurotransmitters open up some sodium ion channels in the postsynaptic dendrite. This allows some sodium ions (Na+) to enter the postsynaptic dendrite, making the membrane potential more positive and bringing it closer to the threshold potential. This increases the likelihood of an action potential. Inhibitory neurotransmitters open up ion channels in the postsynaptic membrane for positive potassium ions (K+) to flow out OR negative chloride ions (Cl-) to flow in. Whether potassium ions go out or chloride ions go in, the postsynaptic cell becomes more negative than the resting membrane potential (further from the threshold potential). This decreases the likelihood of an action potential. |
