rue or false: During the absolute refractory period a neuron will be re-stimulated if it reaches threshold.True false question.TrueFalse

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

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

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

The relative refractory period is where it is more difficult to fire another action potential for a period after the absolute refractory period ends. Which of the following is typically the largest contributor to the relative refractory period?Group of answer choicesThe membrane resistance on the axon is lower than at restThe voltage gated potassium channels are in a state where they cannot openThe membrane potential is more negative than restThe sodium concentration gradient has decreased due to the firing of the previous action potentialVoltage gate sodium channels are in a state where they cannot open
