<prompt> After application of one stimulus, the time period in which the second stronger stimuli can from an impulse is calledAbsolute refractory periodRelative refraction periodLatent refractory periodLocal response  <response>: Ans. b Relative refraction periodRef: Ganong, 25th edp.90Absolute refractory period - No stimulus, no matter how strong, will not excite the nerve during absolute refractory periodRelative refractory period - Stronger than normal stimulus suprathreshold stimulus produces action potential in relative refractory period
