How Do Action Potentials in a Myelinated Axon Differ from Action

question 116

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.
