Given the information below,the neuron with the characteristics listed in choice __________ would have the fastest conduction velocity.
A)myelinated,50 μm diameter
B)myelinated,10 μm diameter
C)unmyelinated,50 μm diameter
D)unmyelinated,10 μm diameter

Question

Quizplus · Accepted Answer

Myelination increases conduction velocity by allowing the action potential to "jump" from node to node, rather than traveling the entire length of the axon. A larger diameter also increases conduction velocity by decreasing resistance to current flow. Therefore, a myelinated neuron with a larger diameter (choice A) would have the fastest conduction velocity.
