myelin sheath Thesaurus Medical Encyclopedia Wikipedia n. The insulating envelope of myelin that surrounds the core of a nerve fiber or axon and facilitates the transmission of nerve impulses. In the peripheral nervous system, the sheath is formed from the membranes of Schwann cells, and in the ...
The light shell surrounding the axon was shown to consist of lipids and lipoproteins, and was suggested to be named myelin. Actually, myelin, considered as a structural entity of nerve fibers, has been known since the mid-19th century, and its name was believed to be generally attributed to...

Myelin Sheath: The myelin sheath is a substance that wraps around the axon of the neuron. The myelin sheath being damaged or degenerating will cause the electric impulses passing through the neuron to become slower and degrade. Answer and Explanation:1 ...
aThe individual myelin layers can be seen in this electron micrograph of a cross section of anaxon (AX). The myelin sheath is formed by an adjacent supportive(glial) cell (SC). 各自的myelin层数在anaxon轴的横断面的这张电子显微照片能看 ()。 髓鞘由毗邻支援(神经胶质细胞) SC. (形成) [...
Myelin is a lipid-rich substance that surrounds some axons within the central and peripheral nervous systems. The sheath is formed by the wrapping of multiple layers of the cellular membrane (mainly lipoprotein) of the myelin-producing cells around the axon. In the central nervous system (CNS) ...
The myelin sheath wraps around the fibers, which are the long, threadlike parts of a nerve cell. The sheath protects these fibers, known as axons, like the insulation around an electrical wire. When the myelin sheath is healthy, nerve signals are sent and received quickly. But when something...
Oligodendrocyte units corresponded to classically described type I/II or type III/IV unit phenotypes which respectively myelinated discrete populations of small and large diameter axons, delineated by a myelinated fire diameter of 2–4 μm (diameter of the axon plus its myelin sheath). Within ...
Myelin repair invivo is increased by targeting oligodendrocyte precursor cells with nanoparticles encapsulating leukaemia inhibitory factor (LIF) Multiple sclerosis (MS) is a progressive demyelinating disease of the central nervous system (CNS). Many nerve axons are insulated by a myelin sheath and t....
