In a medullated nerve fibre, the conduction of impulse is faster due to the presence of

A

pericytes

B

endoneurium and epineurium

C

myelin sheath and nodes of Ranvier

D

Nissl's granules

Text Solution

Verified by Experts

The correct Answer is:
C
Medullated nerve fibres are covered by myelin sheath.The conduction of impulse is faster in medullated nerve fibre due to the presence of myelin sheath and nodes of Ranvier.
