Definition of myelin in English:

myelin

noun 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.
〔剖，生理〕髓磷脂，髓鞘
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

myelinated

Example sentencesExamples

myelination

noun ˌmʌɪəlɪˈneɪʃ(ə)nˌmaɪələˈneɪʃ(ə)n

Example sentencesExamples
