WebMyelin is an electrical insulator, although its function of facilitating conduction in axons has no exact analogy in electrical circuitry. The morphological distinction between white matter and gray matter is the one that is useful for the neurochemist. White matter is composed of myelinated axons, glial cells, and blood vessels. WebIndapamide attenuated the degree of myelin disruption and axon loss, decreased lipid peroxidation in the spinal cord white matter, and reduced extracellular superoxide produced by microglia. en_US: dc.identifier.citation: Michaels, N.
