Question

The ratio of conduction of nerve impulses in medullated and non-medullated fibres is ______.

विकल्प

• 30 : 1

• 20 : 1

• 50 : 1

• 40 : 1

Answer 1

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.
