Myelination is crucial for the proper functioning of the CNS. It increases the speed of nerve impulse conduction and ensures efficient signal transmission over long distances.
- Saltatory Conduction: Myelination enables saltatory conduction, where electrical impulses jump from one node of Ranvier to the next, significantly increasing conduction speed. - Insulation: The myelin sheath acts as an insulator, preventing signal loss and cross-talk between adjacent axons.
