Question 19 of 20

Yes, that is correct. All of the answers provided are correct.

In a myelinated nerve, the impulse leaps from node to node - this is called saltatory conduction. When the nerve is myelinated, this conduction is more rapid and energy efficient than in an unmyelinated nerve. And the greater the diameter of the axon, the thicker is the myelin sheath, therefore saltatory conduction occurs more rapidly in thicker axons.
