Question

Saltatory conduction of nerve impulses occurs in

• A. Amyelinated fibres
• B. Myelinated fibres
• C. Both (a) and (b)
• D. None of the above

Answer 1

The correct option is B Myelinated fibres

The myelinated nerve fibers are the nerve fibers which are covered by the myelin sheet. It is an insulating layer which do not allow nerve conduction all through the length of the nerve cell. So the conduction of impulse takes place at the node where the myelin sheath is not present. It involves the rapid conduction of generated nerve potential. This type of nerve conduction is known as saltatory conduction.

So, the correct answer is option B.
