Myelin speeds the conduction of action potentials along a neuron by
A) increasing the diameter of the axon.
B) inserting additional voltage-gated K+ channels into the membrane.
C) allowing the action potential to ʺjumpʺ over sections of the axon.
D) increasing the resting membrane potential.
E) lowering the threshold at which action potentials are generated.

Question

Quizplus · Accepted Answer

Myelin sheaths enable saltatory conduction, where action potentials "jump" from one node of Ranvier to the next, significantly speeding up signal transmission along myelinated axons.
