How Are Action Potentials Different in a Myelinated Axon and an Unmyelinated

question 68

Multiple Choice

How are action potentials different in a myelinated axon and 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.
