Chapter 11, Problem 8CYR

With respect to the condition of action potentials, which of the following statements is false?

a. Every region of the membrane must be depolarized and triggered to generate an action potential via saltatory conduction.

b. In an unmyelinated axon, every region of the membrane must be depolarized and generate action potentials.

c. Type A fibers are the largest, have the most myelin, and conduct action potentials the fastest.

d. The myelin sheath allows saltatory conduction, in which only the nodes of Ranvier must generate action potentials.
