the fat and protein-containing material that surrounds and protects some nerves

The series of fatty wrappers, formed by special glial cells, that surround the axons of those neurons that must communicate over long distances in the nervous system and that allow for fast propagation of action potentials along those axons. See also nodes of Ranvier.

Stacked specialized cell membrane that forms an insulating layer around vertebrate axons and increases the speed of impulse conduction. It is produced by Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system.

A structure that speeds the movement of action potentials along the axon of a neuron. The sheath is built of Schwann cells, which wrap themselves around the axon of the neuron, leaving small gaps in between known as the nodes of Ranvier.

is the fatty layer of insulation that is wrapped around most large nerve fibres and which allows for rapid, unattentuated conduction of the action potential X Y Z

a fatty layer of material that covers the axons of nerve cells.

the insulating layer that forms around nerves and helps with the transmission of nerve impulses; if the myelin is damaged, the impulses are disrupted. This can cause diseases like multiple sclerosis.

a layer of myelin encasing (and insulating) the axons of medullated nerve fibers

the "white matter" of the brain that serves as an insulator to protect nerves. In Canavan disease, a chemical imbalance destroys the myelin and causes the "white matter" to become spongy, resulting in the disease's incapacitating symptoms

the insulating coating of neuron, made up largely of fat. Covers each axon. Increases speed to make coordination possible. Increases velocity of nerve impulse.

1-200 insulating layers of myelin surrounding nerve fibres in the central and peripheral nervous system.

tube that insulates axons, made of segments of fatty tissue.

Insulating layer of specialized cell membrane wrapped around vertebrate axons. Produced by oligodendrocytes in the central nervous system and by Schwann cells in the peripheral nervous system.

( my-eh-lin) [Gk. myelinos, full of marrow] In a neuron, an insulating coat of cell membrane from Schwann cells that is interrupted by nodes of Ranvier where saltatory conduction occurs.

Layers of specialized glial cells, called Schwann cells, that coat the axons of many neurons.

The fatty layer surrounding the axons of nerves that provides electrical insulation so that impulses can travel. In the peripheral nervous system, myelin is produced by Schwann cells. For more information, see the Wikipedia article.

the fatty substance that surrounds and protects some nerve fibers

layers of cell membranes of the peripheral or central nervous system that wrap nerve fibers providing electrical insulation and increasing the speed of impulse transmission.

A covering made of a special fat that encloses a neuron's axon and allows it to transmit action potentials.

a sheath formed by many layers of the membrane of schwann cells or oligodendrocyte wheel cells that are wrapped tightly around segments of axon in vertebrate nerve; serves as electrical insulation in saltatory conduction

Fatty substance that surrounds some axons.

Myelin sheath is the sheath surrounding the axon of some (the myelinated) nerve cells.

The cover that surrounds many nerve cells and helps to increase the speed by which information travels along the nerve.

A white, fatty covering on nerve axons.

The insulating envelope that surrounds the core of a nerve fiber facilitates the transmission of nerve impulses.
