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 myelin sheath is formed by the compaction of multiple layers of cell membrane derived from either oligodendroglial or Schwann cells. The composition of myelin differs, however, from the composition of most other cell surface membranes in the high proportion of lipid to protein. As in other ...
What cells form myelin in the spinal cord? The myelin sheath of the CNS is formed by ___. Name the following: Nervous tissue cells that form myelin sheaths. What does myelin do for neurons? A. Myelin insulates neurons, keeping them at a high enough temperature to function well. B. Mye...

3. Source of Myelin Sheath: The myelin sheath is formed by specific types of cells. In the peripheral nervous system (PNS), the myelin sheath is produced by Schwann cells. In contrast, in the central nervous system (CNS), oligodendrocytes are responsible for myelin formation. 4. Evaluating ...
Consuelo Guerri, María Pascual, in Neuropathology of Drug Addictions and Substance Misuse, 2016 Introduction Myelin is an important component of brain white matter and is formed by specialized glial cells that ensheath axons, with a lipid-rich insulating membrane that allows the acceleration of the...
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) ...
Myelin sheath Myelin sheaths are formed and maintained by oligodendrocytes (Dhaunchak and Nave, 2007). Myelin assembly and long-term preservation require a number of proteins that are either expressed in the myelin or at the axonal membrane. MOG is localized on the outermost surface of the myeli...
Also found in: Dictionary, Thesaurus, Encyclopedia. myelin [mi´ĕ-lin] the lipid substance forming a sheath (the myelin sheath) around the axons of certain nerve fibers; it is an electrical insulator that serves to speed the conduction of nerve impulses in these nerve fibers, which ...
