Myelinated axons without gaps in the myelin (nodes of Ranvier)conduct impulses more efficiently than axons with nodes of Ranvier.

Question

Quizplus · Accepted Answer

Myelinated axons with nodes of Ranvier conduct impulses more efficiently because the nodes allow for rapid saltatory conduction, where the impulse jumps from node to node, increasing the speed of the signal transmission. Axons without gaps in the myelin would have a continuous conduction, which is slower.
