प्रश्न
Distinguish between Impulse conduction in a myelinated nerve fibre and unmyelinated nerve fibre
Advertisements
उत्तर
| Impulse conduction in a myelinated nerve fibre | Impulse conduction in an unmyelinated nerve fibre | |
| 1. | In a myelinated nerve fibre, the action potential is conducted from one node to another. | 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 faster | The conduction of impulses is slower. |
| 3. | It has less energy. | It has more energy. |
| 4. | In these, buoyancy and the transmission of inspiration are found. | In these, inspiration transmission is found in the form of self-propagating electrical waves. |
