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 a myelin sheath form?
A myelin sheath forms when oligodendrocytes in the central nervous system or Schwann cells in the peripheral nervous system wrap around axons, creating multiple layers of membrane rich in lipids. This myelin sheath acts as an insulating layer that speeds up the transmission of electrical signals along the axon.
what is the covering of a fatty material that speeds up the passage of a nerve impulse?
The covering of a fatty material that speeds up the passage of a nerve impulse is called the myelin sheath. It is made of lipids and proteins and acts as an insulating layer around the axon of a neuron, allowing for faster transmission of electrical signals.
Do myelin fibers contain any collagen?
Myelin fibers themselves do not contain collagen. Myelin is primarily composed of lipids and proteins, specifically a type of protein called myelin basic protein and other associated proteins that help in its structure and function. Collagen is a structural protein found in connective tissues, but it is not a component of the myelin sheath surrounding nerve fibers.
Is a wrapping produced by some glial cells that are primarily made up of lipids?
Yes, the wrapping produced by certain glial cells, primarily oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system, is called myelin. Myelin is composed mainly of lipids and proteins, forming a protective sheath around axons. This myelin sheath enhances the speed of electrical signal transmission along the nerve fibers.
The myelin sheath is manufactured by Schwann cells in the form of a bilayer made of what?
The myelin sheath is manufactured by Schwann cells in the form of a bilayer made of lipids (fats). This lipid bilayer consists of layers of membrane that wrap around the axon of a neuron, providing insulation and allowing for faster transmission of nerve impulses.
What do myelin sheath membranes lack which makes them good insulators?
Channel and carrier proteins
What increases the speed of the transmission?
Myelin Sheath Myelin Sheath
Myelin is largely composed of?
Myelin is largely composed of lipids, particularly phospholipids and cholesterol. These lipids form a sheath around the axons of neurons, providing insulation and enhancing the speed at which electrical signals can travel along the neurons.
What increases the speed of impulse transmission?
Myelin Sheath Myelin Sheath
What are schwann cell nucleus'?
myelin sheath peace.love.faith
What is myelin sheath on nerve fibers?
The endoneurium surrounds and protects the myelin sheath.
