NettetMyelin is an electrical insulator that insulates nerve cell axons to increase the speed at which information (encoded as an electrical signal) travels from one nerve cell body to another (as in the central nervous system) or from a nerve cell body to a muscle (as in the peripheral nervous system). NettetMultiple sclerosis (MS) is a neurodegenerative disease that affects the central nervous system, including the brain and spinal cord. The disease causes inflammation and damage to the myelin sheath, which is the protective covering that surrounds nerve fibers.

"NettetNerve Insulation Function and Dysfunction The myelin sheath is a protective, fatty covering that surrounds your nerve fibers, comparable to the insulation that surrounds electrical cables. This covering allows electrical impulses between nerve cells to move quickly back and forth. Without this protection, these signals would be slow and sluggish. " - Insulates nerve fibers

Two are especially critical: the axial (longitudinal) resistance of the fiber to electrical current (r i and r o in Figure 1 A), and the capacitance of axon surface that must be charged to threshold to regenerate a nerve impulse farther down the axon.

NettetMyelinated Neuron Diagram. Myelin is a thick sheath of lipoprotein that insulates the nerve fibres of the myelinated neurons. It is not a continuous sheath and is absent at regular intervals. The region where the myelin sheath is absent is termed the node of Ranvier.
