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 function of myelin is to prevent impulses to escape from the nerve at the wrong point
Myelin insulates and protects the nerves in the central and peripheral nervous system.
The function of the myelin sheath is to speed up the impulses as they propagate along the myelinated fibers. This keeps the electrical current from leaving the axon.
Myelin acts as the insulation for the nerve cells. It grossly enhance the speed of nerve conduction.
a wrapping of myelin around certain nerve axons serving as an electrical insalator that speeds nerve impulses to muscles and other effectors
Increases the speed of transmissions across the axon, but the main purpose of myelin is to cover neuron cells so that it can conduct action potential more quickly.
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.
Myelin insulates and protects the nerves in the central and peripheral nervous system . It is essential for efficient nerve cell communication (signals) and body functions such as walking,
They secrete the myelin sheath that surounds the neuronal axons inside the CNS
The myelin sheeth helps keep signals (like electrical impulses) within the axon so that they can get to the cell body (of the neuron). This is necessary for muscles to contract (to move). If myelin is lost the signal or "electrical impulse" is less and less which has an affect on muscle function because there isn't enough signal to stimulate or "tell" the muslce to move.
A fatty substance that is wrapped around the shaft of axons in the nervous system and whose function is to insulate neurons and speed up the neural impulse?
That substance is called the myelin cell or myelin sheath.
Myelin (sheath) is a white fatty covering (of proteins and phospholipids) that wrap around axons (long nerve fibers that deliver impulses from one neuron to another) insulating them to help them fire faster.
The Schwann Cell produces the myelin sheath and functions in repair and regeneration of damaged nerves
the plasma membrane surrounding a Schwann cell of a myelinated nerve fiber and separating layers of myelin
Nerve impulse is an electrical current, which flows across the axons. So most of the neurons are surrounded by myelin sheath. This sheath gives insulation to the axons. Brain can not function without this insulation.

Some lipids act as an insulator, similar to the covering on an electrical cord. This is called a myelin sheath.
Myelin sheath is the "cover" if you like of nerves. It's structure is important in helping pass the nerve impulses along it's axon, from the body, to the terminal buttons. Long story short, a degeneration of the Myelin sheath leads to interrupted, or non existent impulses, and causes a very well known disease, called MS (multiple sclerosis)
They both form myelin sheaths, but Schwann cells only do so in the peripheral nervous system.
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… Read More
What is the purpose of the myelin sheath? RIGHT Answer--- The myelin sheath serves as an insulator for the axon.
Myalin sheath has a protective function. They are very tough. Myalin sheaths are protected by other myalin sheaths and the skull bones and vertebrae.
There are different types of glial cells and they each have a separate function. You have astroglia, microglia and oligodendroglia. Some are for structural integrity, some for cleaning up debris and some are used to make myelin.
In the central nervous system, oligodendrocytes make the myelin sheaths around axons via cytoplasmic extensions. In the peripheral nervous system. The Schwann cells perform the same function but the entire cell wraps around a portion of the axon.
A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron.
Neurolemma is just an outer shell of the myelin sheath, it's function is to protect a myelinated cell from injury and aid in its healing from injury by allowing information to travel faster to the brain that an unmyelinated cell.
Multiple sclerosis causes the myelin sheaths around the axons in the neurones to be destroyed. The myelin is an insulator and so if it is not present, ions will flow across the nuerone membrane, thus slowing or even inhibiting action potential(nerve impulses)
The myelin sheath, an insulating layer around the axon of a neuron, is mainly made up of H20 (40%); the dry mass of myelin is made up of mostly lipids (70 - 80%), and the rest is proteins (30 - 15%). There are three types of myelin protein, one of which is myelin basic protein. The lipid that mostly makes up myelin is called galactocerebroside.

oligodendrocytes are glia cells that produce myelin
Oligodendrocytes produce the myelin sheath for neurons in the CNS. Schwann cells form the myelin sheath in the PNS.
Myelin is the material that surrounds and protects the spinal cord, and it helps conduct information signals up and down the cord. Myelin is rich in protein.
Myelin sheath is a covering of neurons and it does not travel.
The endoneurium surrounds and protects the myelin sheath.
the disease that strips myelin from nerves is meningitis
Multiple sclerosis affects the myelin sheath.
Axons are located within the neurons and are extremely tiny. They receive information from a neighboring dendrite (also part of a neuron). The axon is surrounded by what is called a myelin sheath--which acts as a sealer for the axon. When the information in the form of electrical signals passes down the axon, the myelin sheath will inhibit the ions from escaping. However, in multiple sclerosis, the myelin on the action is degenerated and cannot… Read More
A disease that effects the myelin sheath is multiple sclerosis (MS). The function of the myelin sheath is to act as an insulator for the nerve cell. It's kind of like the rubber casing found on the outside of wires to protect the electron movement inside and allow us not to get shocked. MS causes the destruction of the myelin sheath which causes it to scar and harden and as a result we short circuit… Read More
Axons are coated in a fatty substance called myelin - a "myelin sheath". It insulates and protects the cell body of neurones. The myelin doesn't completely coat the axon: there are small gaps between the myelin, called the nodes of Ranvier.
Oligodendrocytes produce myelin in the brain and spinal cord. This process is known as myelination and the myelin will warp itself around the neurons.
The schwann cell is the myelin sheath.
Oligodendrocytes are specialized neurolgical cells that produce myelin sheath.
the Myelin Sheath Myelin Sheath Your welcome I had to look for it
The myelin sheath wraps around the around the axon of a neuron. The gaps of the myelin sheath are not insulated and are therefore capable of generating electrical activity.
If you mean the part of a neuron, then an axon transmits the signal created by the nucleus to another neuron. Myelin, the coating around the axon, helps make this process faster.
CNS: oligodendrocytes make the myelin, they cooperate in the formation of a myelin sheath along the axon, this is the process of myelination. Each oligodendrocyte produces segments of several axons. PNS: schwann cells make the myelin, each schwann cell can myelinate one segment of a single axon and they work together ot form the myelin sheath.
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
Oligodendrocytes are glial cells that function in the CNS--the brain and spine. They provide insulation (myelin sheaths) in several locations, possibly multiple neurons. Meanwhile, schwann cells are glial cells that function in the PNS--peripheral nervous system, everything outside the brain and spine. Individually, they wrap around axons of nerves, forming individual segments of myelin sheaths. They, unlike oligodendrocytes, can guide repairs to damaged axons. Damage to the nerves in the brain are not so easily… Read More
