A student asks for an explanation of the absolute refractory period of the action potential. What response by the professor is best?
A)A stronger than normal impulse will evoke another response.
B)No stimulus is able to evoke another response at this time.
C)Multiple stimuli can produce more rapid action potentials.
D)The hyperpolarized state means a weaker stimulus produces a response.

Question

Quizplus · Accepted Answer

During the absolute refractory state of the action potential, no stimulus is able to evoke another response from the cell. A stronger than normal impulse may generate a response in the relative refractory period. This period of time is not related to the number of stimuli. A hyperpolarized state means a stronger than normal stimulus would be needed to generate a response.
