Saltatory conduction is aided by _____ located at _____.
A) sodium-potassium pumps;terminal buttons
B) sodium and potassium channels;nodes of Ranvier
C) calcium channels;nodes of Ranvier
D) glial cells;nodes of Ranvier

Question

Quizplus · Accepted Answer

Saltatory conduction is a faster mode of conduction in myelinated axons, and it occurs as a result of action potentials jumping from one node of Ranvier to the next. This is aided by the presence of voltage-gated sodium and potassium channels located only at the nodes of Ranvier, which allow for the rapid depolarization and repolarization of the membrane necessary for action potential propagation. Therefore, choice B is the correct answer.
