The fact that action potentials occur only at the nodes of Ranvier is the basis for:
A)Increased energy consumption in myelinated neurons
B)Saltatory conduction
C)Slower conduction speed in myelinated neurons
D)Faster conduction speeds in unmyelinated neurons

Question

Quizplus · Accepted Answer

Saltatory conduction is the process of rapidly transmitting action potentials down a myelinated axon by "jumping" between nodes of Ranvier. This allows for faster conduction speeds and conserves energy compared to unmyelinated neurons, where action potentials must travel the entire length of the axon.
