Myelin sheath, a sleeve that protects a part of your nerve cells, and how it's related to multiple sclerosis. Read to learn more about its functions and how to protect it from damage.
The myelin sheath is a protective covering that surrounds fibers called axons, which are the long thin projections that extend from the main body of a nerve cell or neuron. This sheath is composed ...
Thin myelin sheaths as the hallmark of remyelination persist over time and preserve axon function. PNAS , October 2017 DOI: 10.1073/pnas.1714183114 Cite This Page : ...
Nerve fibers are surrounded by a myelin sheath. Scientists at the Technical University of Munich (TUM) have now made the first-ever "live" observations of how this protective layer is formed. The ...
The myelin sheath surrounding the axons, or nerve fibers, can be compared to the insulation covering an electric wire. Without it, the rapid propagation of electric signals would not be possible.
One way axonal function may be hindered is through damage to the myelin sheath, a fatty coating that wraps around axons. Similar to the plastic or rubber used to insulate a cable, ...
Now, researchers from the University of California San Francisco have identified an over-the-counter antihistamine called clemastine that can reverse damage to the myelin sheath and, what’s more ...
In the current study, the research groups were able to show that myelin, which was previously viewed as a solely protective structure, can actually threaten the survival of the axons. This is the case ...
The myelin sheath of nerve fibers was first discovered and described by Rudolf Virchow in 1854. Myelin is composed of about 40% water and the dry mass is composed of about 80% lipids and 20% protein.
In this image, an axon appears in green, while abnormal protein clumps (amyloid, red) lodge in tiny channels within the myelin sheath. Amyloid aggregates form filament-like strands across the ...
