The fastest possible conduction velocity of action potentials is observed in ________.
A) thin, unmyelinated neurons
B) thin, myelinated neurons
C) thick, unmyelinated neurons
D) thick, myelinated neurons

Question

Quizplus · Accepted Answer

Thick, myelinated neurons have the fastest possible conduction velocity of action potentials due to their ability to conduct saltatory conduction, where the action potential jumps from one node of Ranvier to the next, rather than traveling the entire length of the axon. This increases the speed of conduction compared to unmyelinated neurons and thin myelinated neurons.
