When comparing saltatory conduction to contiguous conduction, saltatory conduction
A)is the only method that occurs along both dendrites and axons
B)is the only method that utilizes a positive feedback cycle
C)requires more Na+-K+ activity after repolarization is complete
D)causes the loss of fewer K+ ions during repolarization
E)occurs along unmyelinated axons

Question

Quizplus · Accepted Answer

Saltatory conduction occurs along myelinated axons and results in the loss of fewer K+ ions during repolarization compared to contiguous conduction. This is because in saltatory conduction, the action potential jumps from one node of Ranvier to the next, skipping over the myelinated sections of the axon where K+ ions would otherwise be lost.
