Which of the following regarding "saltatory conduction" is correct?
A)Saltatory conduction occurs in unmyelinated nerve fibres.
B)Saltatory conduction is slower than conduction by local current flow because the myelin acts as an insulator to slow the impulse.
C) Saltatory conduction involves the impulse jumping from one node of Ranvier to the adjacent node.
D) Saltatory conduction refers to the action potential spreading from one Schwann cell to the adjacent Schwann cell.

Saltatory conduction involves the impulse jumping from one node of Ranvier to the adjacent node. Myelin sheaths actually assist in the conduction of nerve impulses by speeding up the time it takes for the impulse to travel along the axon. This is because the myelin acts as an insulator, preventing the impulse from leaking out through the axon membrane.
