Question

Distinguish between Impulse conduction in a myelinated nerve fibre and unmyelinated nerve fibre

Distinguish Between

Solution

  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.
