Myelin is the material that covers the spinal cord. It protects the cord from damage. If the myelin wears away, then a person is said to have Multiple Sclerosis.
Myelin makes it easier for acons to transmit signals- it speeds there work.
Myelin is composed of about 80% lipid and about 20% protein. Some of the proteins that make up myelin are myelin basic protein (MBP),myelin oligodendrocyte glycoprotein (MOG), and proteolipid protein (PLP). Myelin is made up primarily of a glycolipid calledgalactocerebroside. The intertwining of the hydrocarbon chains of sphingomyelin serve to strengthen the myelin sheath.There are quite a few disease (multiple sclerosis, optic neuritis, transverse myelitis..) involved in the destruction of the axon myelin sheath also known as myelin sheath.http://en.wikipedia.org/wiki/Myelin

Myelin sheath is the insulation of the CNS (central nervous system). Its helps electrical signals move along nerves. Basically, its synonymous with insulated wire. Again the insulation help the signal move in a smooth and controlled fashion through out the body.
there are specialized cells in the nervous system produce and form the myelin in the central nervous system (brain & spinal cord) by oligodendrocytes in the peripheral nervous system by schwann cells
Form myelin in the brain and spinal cord....
myelin sheath
Muscles and glands are not myelinated. It is the axon of a neuron that is myelinated. The myelin forms a layer called myelin sheath that makes the nervous system function properly.
The function of the myelin sheath is to insulate the axon of the neuron. When there are gaps in the sheath, known as nodes of Ranvier, the nerve impulse can jump from gap to gap, thus increasing greatly the speed of conduction of the nerve impulse. This is known as saltatory conduction.

Myelin sheaths insulate nerve fibers
The fatty tissue surrounding the axon of a neuron is called myelin.
Myelin is a lipid which surrounds the axon and provides for faster and more complex neural conduction.

Myelin is a fatty substance that insulates and protects nerve cells and allows them to transmit electrical signals quickly.
Some lipids act as an insulator, similar to the covering on an electrical cord. This is called a myelin sheath.
A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron.
