A) Saltatory conduction is seen in non-myelinated nerve fibres
B) Nissl's granules are found in muscle fibres
C) Non-myelinated nerve fibres do not possess nodes of Ranvier
D) Non-myelinated nerve fibres are completely enclosed by myelin sheath
Correct Answer: C
Solution :
In myelinated nerve fibre, the myelin sheath is not continuous and remains interrupted at some places. These are known as nodes of Ranvier. These help in the saltatory conduction of nerve impulse. The non-myelinated nerve fibres do not possess nodes of Ranvier.
