Which of the following is false or incorrect?
A)An inhibitory postsynaptic potential occurs if the inhibitory effect is greater than the excitatory,causing hyperpolarization of the membrane.
B)An excitatory postsynaptic potential occurs if the excitatory effect is greater than the inhibitory effect but less than threshold.
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, resulting in depolarization of the membrane and reaching the threshold for an action potential to be generated. So the statement "A nerve impulse occurs if the excitatory and inhibitory effects are equal" is false.
