| 释义 | oligodendroglia noun[ plural or U ] anatomy specializeduk /ˌɒl.ɪ.ɡəʊˌden.drəˈɡlaɪ.ə/ us /ˌɑː.lɪ.ɡoʊˌdenˈdrɑːɡ.li.ə/ cells in the nervous system that produce myelin(= a substance that surrounds and protects nerves): During the early postnatal period, these axons are wrapped in the insulating substance myelin, produced by oligodendroglia. Without the oligodendroglia cells forming myelin, nerve signals would become slowed or even completely blocked. In later stages of MS, the oligodendroglia cells are destroyed, which produces multiple demyelinated areas on the axons of the neurons. These problems with movement occur because the loss of the oligodendroglia cells weaken the electrical impulses from the brain. A direct effect of the antibodies on the oligodendroglia has not yet been demonstrated.
