Solution
The ratio of conduction of nerve impulses in medullated and non-medullated fibres is 50 : 1.
Explanation:
Electrical impulses in neurons are accelerated by myelin. The nerve impulse is transmitted from one Ranvier node to the next. As a result, the nerve impulse conduction ratio in medullated versus non-medullated fibres is 50:1.
