Which of the following correctly explains why myelinated axons conduct action potentials faster than unmyelinated axons?
Show answer and explanation
Correct answer: Myelin insulates the axon, allowing saltatory conduction between nodes of Ranvier.
Myelin insulates the axon and forces action potentials to jump between the nodes of Ranvier (saltatory conduction), significantly increasing conduction velocity compared with continuous propagation in unmyelinated axons.
