"It seems that the total amount of the myelin in the myelin sheaths is relatively preserved," says Grutzendler. Nerves are coated in myelin, but have tiny gaps called "nodes of Ranvier" where the ...

New research reveals that Alzheimer's disease may impair nerve function not by reducing myelin, but by altering the proteins ...

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, ... Instead, it is divided into segments. These can vary in length and are separated by gaps known as nodes of Ranvier.

Nerves are coated in myelin, but have tiny gaps called “nodes of Ranvier” where the nerve is exposed to boost signals. Right next to these gaps are “paranodes,” where the myelin sticks tightly to the ...

A new study reveals that neural stem cell grafts can generate new myelin in the central nervous system, offering hope for ...

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.
