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
The myelin sheath is a protective covering around nerve fibers that helps speed up the transmission of electrical signals in the nervous system. It acts like insulation on a wire, allowing signals to travel faster and more efficiently. The function of the myelin sheath is to enhance the speed and efficiency of nerve signal transmission.
Form myelin in the brain and spinal cord....
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.

Multiple sclerosis (MS) is a disease that affects the central nervous system, including the brain and spinal cord. In MS, the immune system mistakenly attacks the protective covering of nerve fibers called myelin. This damages the myelin, leading to disruptions in the transmission of nerve signals. As a result, the formation and function of myelin in the nervous system are impaired, causing symptoms such as weakness, numbness, and difficulty with coordination and balance.
Myelin is a lipid which surrounds the axon and provides for faster and more complex neural conduction.
Myelin is found in the nervous system and is produced by cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Its function is to insulate and protect neurons, as well as speed up the transmission of electrical impulses along nerve cells.
Myelin is a fatty substance that surrounds nerves and helps facilitate the rapid transmission of electrical impulses. It helps to speed up and enhance the efficiency of nerve signal transmission in the body. The presence of myelin is crucial for proper nerve function and the coordination of various bodily processes.
The main function of glial cells, specifically oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system, is to provide insulation to neurons through the formation of myelin sheaths. These myelin sheaths wrap around the axons of neurons, which helps to increase the speed and efficiency of electrical signal conduction along the neuron.

Building myelin sheaths and cell membranes requires an adequate supply of essential nutrients, particularly fatty acids like omega-3 and omega-6. Phospholipids are also crucial for membrane structure and function. Additionally, the presence of certain proteins, such as myelin basic protein, is necessary for the formation and maintenance of myelin sheaths.
