Myelinated axons conduct action potentials about _________ unmyelinated axons do.
A) as fast as
B) half as fast as
C) six times faster than
D) 20 times faster than

Question

Quizplus · Accepted Answer

Myelinated axons conduct action potentials about six times faster than unmyelinated axons. This is because the myelin sheath acts as an insulator, allowing the electrical signal to jump from one node of Ranvier to the next, rather than traveling down the entire length of the axon. This process, called saltatory conduction, speeds up the transmission of the action potential.
