Thick nerve

Vedclass · Answer

(B) The velocity of nerve impulse conduction is directly proportional to the diameter of the nerve fibers. As the diameter of the nerve fiber increases,the internal resistance to the flow of ions decreases,which allows the action potential to propagate more rapidly along the axon. Therefore,thick nerve fibers conduct impulses faster than thin nerve fibers.
