∙ 15y agoMyelin is supplied by Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system. Myelin is essentially many layers of cell membrane formed by the multiple wrappings of Schwann cell or oligodendrocyte membranes around the axon of a neuron.

Our body has a Peripheral Nervous System that branches from the spinal cord to carry information related to sensory input, while our brain's Central Nervous System determines how to act on that input. Each of these systems synthesizes myelin in a different way.

What is the function of myelin?
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.
The main component of the myelin sheath is?
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
How does the presence of myelin help axons work?
Myelin makes it easier for acons to transmit signals- it speeds there work.
The interior of the is white due to the high concentration of myelin-sheathed axons?
Cerebrum
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.
How is myelin formed within the central nervous system?
The glial cells that surround the neurons produce myelin.
Formed by schwann cells in the PNS?
Myelin sheath
The myelin sheath that covers many CNS axons is formed by?
Oligodendrocytes
What type of cells produce the myelin sheath in the central nervous system?
Oligodendrocytes and Schwann cells both produce myelin. Oligodendrocytes produce myelin in the CNS, whereas Schwann cells produce myelin in the PNS. CNS refers to central nervous system PNS refers to peripheral nervous system
What insulates nerve fibers?
Myelin sheaths insulate nerve fibers
What is the definition of myelin sheath?
A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron.
It insulates the axon of the neuron?
An insulating layer that surrounds the axon is a myelin sheath.
What increases the speed of the transmission?

What increases the speed of impulse transmission?

How does nicotine affect the myelin production?
Nicotine stimulates CREB phosphorylation which regulates the expression of myelin basic protein and myelin oligodendrocyte glycoprotein.
What is the fatty tissue that covers axons and speeds up impulses as they travel from cell to cell?
That substance is called the myelin cell or myelin sheath.
