Vedclass · Answer

(C) In myelinated nerve fibres, the myelin sheath is not continuous and remains interrupted at some places. These gaps are known as nodes of $Ranvier$.These nodes help in the saltatory conduction of nerve impulses.Non-myelinated nerve fibres do not possess nodes of $Ranvier$ because they lack the myelin sheath interruptions.Therefore, the statement that non-myelinated nerve fibres do not possess nodes of $Ranvier$ is correct.
