Which of the following is NOT true about the refractory period?

Physiology Test Question

	(A) It is thought that the refractory period is caused by the hyperpolarization phase of the action potential.
	(B) The refractory period is important in preventing the overlap of succeeding action potential.
	(C) The absolute refractory period refers to that time during which a stronger stimulus will lead to the generation of a new action potential.
	(D) The relative refractory period refers to that time during which a stronger stimulus will lead to the generation of a new action potential.
	(E) The relative refractory period coincides with the hyperpolarization phase of the action potential.
