Question

Saltatory conduction is associated with those nerve fibres that have nodes of Ranvier.

• A. True
• B. False

Answer 1

The correct option is A True

The myelin sheath acts as biological electrical insulation, creating a region of the high electrical resistance of the axon. The nodes of Ranvier are the gaps that are present between the adjacent myelin sheaths on an axon.

The nerve impulse generated faces resistance at the sites where myelin sheath is present but not at the sites of nodes of Ranvier. Thus the action potential jumps from one node to other nodes. This type of conduction is saltatory conduction and associated with nerve fibers that possess nodes of Ranvier.

So, the given statement is true.
