Impulse conduction in a myelinated nerve fibre

Impulse conduction in non myelinated nerve fibre

1. Conduction of nerve impulse is faster by twnety times.

2. It uses less energy because only nodesare depolarized.

3. It uses less energy because only nodes are depolarizsed.

4. Ion exchange occurs at nodes only.

1. It is slow.

2. It is smooth.

3. It uses more energy because whole of fibreis depolarized.

4. Ion exchange occurs through out.
