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.

The myelin sheath is composed of lipids, which are fats, they make for good protection as well as conductors for the electrical impulses of the brain. That is one reason that young babies need fat in their diets or else they wont get enough and the sheath may not be as developed as it should be.

it is not PROTEINS, you idiot!....they are composed of lipids!!!!

Scwhann cells, a type of glial cell, wrap their membranes around neuronal axons many times to form the myelin sheath.

It is mostly composed of lipids (fats)

Describe the role of the myelin sheath?

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.


What are the parts of nerve or neurons?

A neuron is a nerve cell, so it has all the parts of an animal cell, plus some specialized parts: axon, dendrites, and perhaps a myelin sheath for insulation.


Where do Nodes of Ranvier lie between?

They are more or less equally spaced. The size of the nodes span from 1–2 µm whereas the internodes can be up to (and occasionally even greater than)1.5 millimeters long, depending on the axon diameter and fiber type.


Gaps between segments of oligodendrocytes or between individual schwann cells are called?

The spaces along the axon and between the myelin sheath are known as the nodes of Ranvier. They are responsible for speeding up the signals that are transmitted along the axon of the nerve. While the myelin sheath consists of many layers that protect the axon, the nodes of Ranvier are uncovered, giving them the ability to produce an electrical charge.


Explain the importance of the myelin sheath?

Myelin is a fatty substance that insulates and protects spinal nerve cells, and allows for faster signal transmission. Therefore as myelin increases in children, their coordination improves. http://www.brainandspinalcord.org/blog/2008/07/can-oxygen-tbi-treatment-cause-more-harm-than-good/
