The myelin sheath forms a protective layer over nerves. However, it is not present on all nerves. Retinal nerves for instance normally are devoid of myelin.
Myelin Sheath
Myelin Sheath
Schwann cells produce myelin in peripheral nerves. Schwann cells wrap around the axon of a neuron to form the myelin sheath, which helps to insulate and speed up the conduction of nerve impulses.

The autoimmune disease that results in the destruction of myelin sheaths is called multiple sclerosis (MS). This condition leads to disruption in the transmission of signals along the nerves, causing a range of symptoms including weakness, numbness, vision problems, and difficulties with coordination and balance.
The myelin sheath surrounding nerves.
Like many names of diseases and conditions, adrenoleukodystrophy is a name that actually describes the problem or symptoms.A dystrophy is a damage or loss of something.Leukodystrophies involve loss of the myelin sheath (insulating wrapping around nerves). Myelin is white, and "leuko" comes from the Greek word for "white." So a leukodystrophy is a loss of or damage to white stuff (myelin). Without the myelin, the nerves do not conduct signals properly, just the way uninsulated wiring may not properly conduct electricity because it is grounded out along the way.Adrenoleukodystrophy is a form of leukodystrophy in which the condition damaging the myelin also damages the brain and leads to failure of the adrenal glands. It is also called "Addison-Schilder Disease," "Siemerling-Creutzfeldt Disease," and "Schilder's disease" but these names merely recognize those who described it for medicine and science, showing it to be a specific condition.

Myelin sheath is the "cover" if you like of nerves. It's structure is important in helping pass the nerve impulses along it's axon, from the body, to the terminal buttons. Long story short, a degeneration of the Myelin sheath leads to interrupted, or non existent impulses, and causes a very well known disease, called MS (multiple sclerosis)
Myelin is the insulating "sheath" that surrounds nerves in your body. When the myelin breaks down, false signals make it into the nerves, sometimes causing pain, and sometimes causing muscle spasms.
Protects the axon. The "Myelin Sheath" serves as an insulator to protect nerves.
