Neuropathy Knowledge What Is Myelin

Today's post from sciencedaily.com (see link below) is the third part of a series from the same source providing readers with explanations and information about many of the medical terms they hear when researching neuropathy, or sitting in the doctor's surgery and talking about it. Today it explains the word 'Myelin' and gives related definitions of other words associated with the workings of myelin. When the myelin sheath is damaged that can be one of the main causes of neuropathy and your pain. Worth following the links if you have the time. Other posts about myelin can be found to the right of this blog.

Myelin
Science Daily via Wikipedia

Myelin is an electrically insulating phospholipid layer that surrounds the axons of many neurons.

It is an outgrowth of glial cells: Schwann cells supply the myelin for peripheral neurons while oligodendrocytes supply it to those of the central nervous system.

The main consequence of a myelin layer (or sheath) is an increase in the speed at which impulses propagate along the myelinated fiber.
