Multiple Choice
Which statement is not accurate about the absolute refractory period?
A) Another stimulus, regardless of its strength, cannot initiate another action potential during this period.
B) During this period, voltage-gated Na+ channels open, then close but are inactivated.
C) Immediately following this period, the membrane can experience another action potential if the stimulus is strong enough.
D) This period occurs during the after hyperpolarization phase of the action potential.
E) This period ensures a unidirectional spread of the action potential down a nerve fiber.
