Myelin is a lipid insulation produced by the?
Myelin is a lipid insulation produced by the cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. It wraps around nerve fibers to help speed up the transmission of electrical impulses along the nerve cells.
Is myelin a connective tissue?
No, myelin is not a connective tissue. Myelin is a lipid-rich material that forms a protective sheath around nerve fibers in the central and peripheral nervous systems. It is essential for the proper functioning of the nervous system by insulating and speeding up the transmission of nerve impulses.
What is a wrapping produced by some glial cells that contains 80 percent lipid and 20 percent protein?
Myelin sheath is the wrapping produced by some glial cells that contains 80% lipid and 20% protein. It acts as an insulating layer around nerve fibers, speeding up the transmission of electrical signals along the nerve cells.
What are examples of a lipid bi-layer?
The cell membrane is a lipid bilayer composed of phospholipids, cholesterol, and proteins. Liposomes, which are artificial vesicles with a lipid bilayer structure, are also used in drug delivery systems and research applications. Additionally, myelin sheaths that surround nerve cells are made up of lipid bilayers.
What is the primary function of the myelin sheath is to?
Myelin is a lipid which surrounds the axon and provides for faster and more complex neural conduction.
The layer of lipid around an axon is called?
The layer of lipid around an axon is called myelin sheath. It acts as an insulator, allowing for faster transmission of nerve impulses along the axon.
Myelin contains a high proportion of?
lipid perhaps...
What iscomposed of lipid material and covers axons?
The myelin sheath is composed of lipid material and covers axons.
Myelin is a lipid insulation produced by the?
Myelin is a lipid insulation produced by the cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. It wraps around nerve fibers to help speed up the transmission of electrical impulses along the nerve cells.
The multi-layered covering composed of lipid and protein that surrounds most of the axons of the human body?
myelin sheath
What is the white lipid material that insulates the axon of a neuron?
The white lipid material that insulates the axon of a neuron is called myelin. In the central nervous system, myelin is created by oligodendrocytes while in the peripheral nervous system the myelin is created by Schwann cells. The purpose of myelin is to speed up action potentials. It's important to know that the myelin does not coat the axon entirely; each sheath of myelin is separated by a gap, called a node of Ranvier. These gaps are responsible for the quick transport of action potentials, due to the fact that the potentials can "jump" from node to node rather than having to travel down the entire length of the axon (this is called saltatory conduction).
What is a wrapping produced by some glial cells that contains 80 percent lipid and 20 percent protein?
Myelin sheath is the wrapping produced by some glial cells that contains 80% lipid and 20% protein. It acts as an insulating layer around nerve fibers, speeding up the transmission of electrical signals along the nerve cells.
Why is the white matter of the spinal cord white?
The white matter of the spinal cord appears white due to the myelin sheaths surrounding the axons of neurons. Myelin is a fatty substance that acts as an insulator, allowing for faster transmission of nerve impulses. The high lipid content of myelin gives the white matter its color.
What are all the leukodystrophies caused by?
All of the leukodystrophies are caused by either a defective protein component of myelin, or by a malfunctioning enzyme that interacts with one of the protein or lipid constituents
What cell is insulated by a fatty layer?
Nerve cells, or neurons, are insulated by a fatty layer called myelin. This myelin sheath helps to insulate and protect the axon, which allows for faster transmission of electrical impulses along the neuron.
What are examples of a lipid bi-layer?
The cell membrane is a lipid bilayer composed of phospholipids, cholesterol, and proteins. Liposomes, which are artificial vesicles with a lipid bilayer structure, are also used in drug delivery systems and research applications. Additionally, myelin sheaths that surround nerve cells are made up of lipid bilayers.
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
