A refractory period is a time in which the plasma membrane becomes Blank______ to further stimulation.Multiple choice question.less sensitivemore sensitive

After a nerve cell responds to a stimulus, the period of time when the cell cannot respond again, regardless of the strength of stimulus, is called the refractory period.

During the absolute refractory period, a stimulus of high intensity may trigger a nerve impulse.Group startsTrue or FalseTrue, unselectedFalse, unselected

Which statement regarding refractory periods is true?Select one:Select the correct definitionThey allow neurons to fire an unlimited number of action potentials per unit of time.During the refractory period the cell requires a less intense stimulus to reach threshold.The refractory period arises in part due to the increase in sodium conductance across the membrane.The refractory period arises in part due to the decrease in potassium conductance across the membrane.The refractory period ends when the sodium channels are no longer inactivated
