Question

Give the difference between impulse conduction in a myelinated nerve fibre and unmyelinated nerve fibre.

Answer 1

Impulse conduction in a myelinated nerve fibre -

1. In a myelinated nerve fibre, the action potential is conducted from one node to another.

2. The conduction of impulses is faster.

Impulse conduction in an unmyelinated nerve fibre -

1. In an unmyelinated nerve fibre, the action potential is not conducted from node to node. It is carried along the whole length of the nerve fibre.

2. The conduction of impulses is slower.
