Definition of myelin in English: myelinnoun ˈmʌɪəlɪnˈmaɪələn mass nounAnatomy Physiology A mixture of proteins and phospholipids forming a whitish insulating sheath around many nerve fibres, which increases the speed at which impulses are conducted. Example sentencesExamples - The neurologic symptoms are a result of destruction of myelin, though axons may also be affected.
- It turns out that the bacterium that causes leprosy directly damages a protective sheathing, made of the protein myelin, around many nerve cells.
- They then manipulated them in the laboratory to turn them into specialised cells that form myelin, the insulating layer than surrounds nerve fibres.
- For example, multiple sclerosis involves the progressive destruction of the myelin that insulates neural axons.
- They travel to the brain and mount an assault on a substance called myelin, which acts as a protective sheath around nerve fibers.
Derivatives adjective ˈmʌɪəlɪˌneɪtɪdˈmaɪələˌneɪdəd Physiology Anatomy (of a nerve fibre) enclosed in a myelin sheath. the axons in the central nervous system are generally myelinated Example sentencesExamples - It also preserved many of the myelinated nerve fibers in treated animals, compared to untreated rats and those that did not receive the triple combination, the researchers found.
- Their content of myelinated nerve fibers indicates their origin as branches of the pelvic colonic innervation.

noun ˌmʌɪəlɪˈneɪʃ(ə)nˌmaɪələˈneɪʃ(ə)n Physiology Anatomy Next are areas related to memory, then to spatial orientation and to comprehension of language and then we see myelination in language areas. Example sentencesExamples - Other innovations in this group of animals include an adaptive immune system similar to that of humans, a closed and pressurized circulatory system, and myelination of the nervous system.
