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 axon is surrounded by multilamellar structure of myelin. (E) Myelinated nerve fiber reproduced in vitro by coculture of rat dorsal root ganglion neurons and Schwann cells.

"Myelin requires a lot of lipids [a group of molecules that includes fats] for normal function," Grutzendler says. "In Alzheimer's disease, lipid metabolism could be abnormally affected in a way ...

He suspects the brain routinely taps into myelin for fuel, just at levels too low to detect—except during extreme events like a marathon. But there’s no need to panic, he says.

Running an entire marathon takes a lot of energy. Neuroscientist Carlos Matute knows this: he's run 18 of them. He wondered how runners' bodies get the energy they need to make it to the finish line.

Myelin is an insulating layer of lipids and proteins surrounding nerves. Myelin damage can cause problems with the nerves’ ability to send and receive electrical messages. Inflammatory disorders ...

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: MLA; APA; Chicago; ...

The researchers concluded that "myelin seems to act as an energy source when other brain nutrients are depleted during endurance exercise, and that further research is needed to establish how ...

In this imaging study, brain regions with higher levels of myelin showed lower levels of tau protein deposition, and regions connected by myelin-rich fiber tracts showed reduced spreading of tau ...
