Which of these nerve fibres will have the highest conduction velocity
A)an unmyelinated nerve fibre with conduction velocity = 0.35 m/sec
B)an unmyelinated nerve fibre smaller than nerve fibre a.
C)a myelinated nerve fibre the same size as nerve fibre a.
D)a myelinated fibre larger than nerve fibre a.

Question

Quizplus · Accepted Answer

Myelinated fibres have a higher conduction velocity than unmyelinated fibres. Additionally, larger fibres have a higher conduction velocity than smaller fibres. Therefore, a myelinated fibre larger than nerve fibre a would have the highest conduction velocity.
