In a myelinated axon, action potentials are produced
a. only at the axon hillock.
b. only at the axon hillock and at the nodes of Ranvier.
c. along the entire length of the axon membrane.
d. only under segments of myelin.
Question 2
Action potentials only go in one direction, away from the cell body, because
a. the adjacent prior segment of axon is still at +40mV.
b. voltage-dependent gates are limited in the frequency with which they can open.
c. the adjacent prior segment is still in refractory period.
d. the action potential temporarily disables the sodium-potassium pumps.
