Myelin is important for propagating action potential (AP) because:
A)it increases the AP's conduction speed.
B)it reduces the need for sodium and potassium.
C)it conserves energy.
D)it both increases the AP's conduction speed and conserves energy.

Question

Quizplus · Accepted Answer

Myelin increases the conduction speed of action potentials by allowing them to jump between nodes of Ranvier (saltatory conduction) and conserves energy by reducing the need for continuous ion exchange along the axon.
