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

The disruption of axons—the thread-like part of nerve cells that transmits electrical signals—is associated with Alzheimer's disease. One way axonal function may be hindered is through damage to the ...

The ratio between axon diameter and that of the total nerve fiber (axon and myelin) is 0.6–0.7, a ratio that is well maintained regardless of the axon caliber. The length of the myelin sheath ...

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 ...

The disruption of axons—the thread-like part of nerve cells that transmits electrical signals—is associated with Alzheimer’s disease. One way axonal function may be hindered is through damage to the ...

The evolution of complex nervous systems in vertebrates has been accompanied by, and probably dependent on, the acquisition of the myelin sheath. Although there has been substantial progress in ...

Myelin and Your Nerves. 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 ...

The myelin sheath surrounding the axons, ... Evidence for Myelin Sheath Remodeling in the CNS Revealed by In Vivo Imaging. Current Biology, 2018; DOI: 10.1016/j.cub.2018.01.017; ...

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.

A major component of brain tissue, lipids are fatty compounds that make up 35-40% of all the molecules in the gray matter cell bodies and as much as 78% of the axons’ myelin sheaths in the white ...
