Which of the following is false or incorrect?
A) An excitatory postsynaptic potential occurs if the excitatory effect is greater than the inhibitory effect but less than threshold.
B) An inhibitory postsynaptic potential occurs if the inhibitory effect is greater than the excitatory, causing hyperpolarization of the membrane.
C) A nerve impulse occurs if the excitatory and inhibitory effects are equal.

Question

Quizplus · Accepted Answer

A nerve impulse occurs only if the excitatory effect is greater than the inhibitory effect, causing the membrane potential to reach threshold and trigger an action potential. If the effects are equal, there is no net change in membrane potential and no nerve impulse is generated. Therefore, statement C is false.
