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

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

The _______ is a period of time when a membrane cannot respond to another stimulus (no matter how strong).Multiple Choiceall-or-none periodabsolute refractory periodrelative refractory periodafterpotential period

What is a refractory period for a membrane?Multiple choice question.Initial part of an action potential when Na+ is rushing into the cell.Threshold potential needed to initiate an action potential.Period of time after an action potential when the membrane cannot send another action potential.

A nerve cell can only respond to an unusually strong stimulus during the Blank______ refractory period.Multiple choice question.roughabsoluterelativeapproximate

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.
