How Do Action Potentials in a Myelinated Axon Differ from Action

Multiple Choice

How do action potentials in a myelinated axon differ from action potentials in an unmyelinated axon?

A) Action potentials are slower in myelinated axons because the myelin sheath interferes with the transfer of ions across the membrane.
B) Action potentials jump from node to node in myelinated axons rather than progressing down the entire length of the axon.
C) Action potentials have greater electrical charges in myelinated axons.
D) Action potentials in myelinated axons operate according to the all-or-none law, but action potentials in unmyelinated axons do not.
