Questions and Answers

What is the absolute refractory period?

  • The interval during which a third action potential can be produced at a higher stimulus intensity
  • The interval during which no action potential can be produced, but a graded potential can be produced
  • The interval during which no action potential can be produced, regardless of the stimulus intensity (correct)
  • The interval during which a second action potential can be produced but at higher stimulus intensity

What is the relative refractory period?

What is the purpose of the absolute refractory period?

  • To decrease the speed of action potential propagation
  • To prevent waves summation and tetanus (correct)
  • To increase the speed of action potential propagation
  • To allow for summation of waves and tetanus
