The wave of absolute refractoriness that follows an action potential
 
  A) keeps the action potential from spreading actively back along an axon towards the cell body.
  B) increases the firing rate.
  C) increases the speed of axonal transmission.
  D) produces a second, negative action potential.
  E) produces saltatory conduction.

Question 2

  C) the total refractory period is typically about 1 millisecond.
  D) the sodium-potassium pump cannot repolarize the cell in less than 1 millisecond.
  E) higher rates over excite the neuron.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
