Answer:
Saltatory conduction:
( e ) occurs only in myelinated axons
Explanation:
Saltatory Conduction -
The propagatory action of the potentials along the myelinated axons via one node of Ranvier to next node by increasing the conduction velocity of the action potentials is called the Saltatory Conduction .
The nodes of Ranvier that are uninsulated are the places in axon , which are responsible for the exchange of ions across the axon membrane and further regenerating the action potential between the axon which is insulated by myelin .
