In the Saltatory Conduction of Action Potentials,the Nerve Impulses Jump

Multiple Choice

In the saltatory conduction of action potentials,the nerve impulses jump from one node of Ranvier to another.This occurs because

A) only the nodes contain neurotransmitters.
B) the nodes are very well insulated and conduct impulses rapidly.
C) jumping from node to node prevents the impulse from traveling backward.
D) jumping from node to node ensures that the impulse travels slowly and evenly.
