myelin sheath
(Science: anatomy, neurology) An insulating layer surrounding vertebrate peripheral neurons, that dramatically increases the speed of conduction. It is formed by specialised schwann cells, that can wrap around neurons up to 50 times.
Myelin (MY-eh-lin) A fatty covering that forms a protective sheath around nerve fibers and dramatically speeds the transmission of nerve signals.
myelin sheath
(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.

myelin
a sheath of fatty substance associated with protein that surrounds larger nerve fibers of vertebrates. The sheath permits a greater current flow and thus speeds transmission of nerve impulses.
Sphingomyelin
The backbone of sphingomyelin is sphingosine, an amino alcohol formed from palmitate and serine. The amino terminal is acylated with a by a long-chain acyl CoA to yield ceramide .
Myelin Speeds Up Thought
Most neurons have a fatty outer layer called myelin, which insulates and protects the axons of neurons. In this way, myelin is like the plastic that surrounds electric wires.

Dendrites (from Greek dendron, 'tree') are the branched projections of a neuron that act to conduct the electrical stimulation received from other neural cells to the cell body, or soma, ...
myelin sheaths around the axons of their neurons. This permits much more rapid transmission of nerve impulses — a trait probably as important for active vertebrates as their jaws.

Some axons are wrapped in a myelin sheath formed from the plasma membranes of specialized glial cells known as Schwann cells. Schwann cells serve as supportive, nutritive, and service facilities for neurons.
They are more numerous than the myelinated fibers. They arise from the small cells of the spinal ganglia by T-shaped axons similar to the myelinated.
Acute inflammation with destruction of myelin around nervous fibres in peripheral nerves. The mechanism is auto-immune triggered by myelin present in rabies vaccines prepared with infected brains ...
neurofibril node Regular gaps in a myelin sheath around a nerve fiber; formerly called node of Ranvier.
neurogenic Originating in nervous tissue, as does the rhythmical beat of some arthropod hearts.
