Q12. Distinguish between:
(b) impulse conduction in a myelinated nerve fibre and unmyelinated nerve fibre
Impulse Conduction in a Myelinated Nerve Fibre |
Impulse Conduction in Non-myelinated Nerve Fibre |
1. Impulse travels from node to node. |
1. Impulse travels along the length of the entire nerve fibre. |
2. The speed of conduction is 50 times faster than the non-myelintaed nerve fibre. |
2. The speed of conduction is slower. |
3. Energy expenditure during impulse transmission is less. |
3. Energy expenditure during impulse transmission is more. |
