Which of the following would produce the fastest possible conduction velocity of action potentials?
A) thin, unmyelinated axons
B) thin, myelinated axons
C) thick, unmyelinated axons
D) thick, myelinated axons

Question

Quizplus · Accepted Answer

Thick, myelinated axons conduct action potentials the fastest due to the increased diameter reducing resistance to ion flow and myelination increasing the speed of transmission via saltatory conduction.
