WebJul 7, 2024 · How does myelin help to speed up nerve impulses? Most nerve fibres are surrounded by an insulating, fatty sheath called myelin, which acts to speed up impulses. The myelin sheath contains periodic breaks called nodes of Ranvier. By jumping from node to node, the impulse can travel much more quickly than if it had to travel along the entire ... WebThe myelin sheath acts as an insulating layer that enhances the speed and efficiency of nerve conduction. In MS, the damaged myelin sheath impairs the ability of nerve impulses to be transmitted along the nerves, leading to decreased nerve conduction efficiency.

WebAsked By : Sandra Morales. Myelinated neurons conduct impulses faster than unmyelinated neurons because nerve impulses jump over the myelin sheath rather than travel through it, making the distance to the axon terminal shorter.
