The myelin is the fatty substance that's present in some kind of neurons, structured as an excess of membrane that does several turns around the axon, improving the electrical transmission along the axon. So, the transmission of electrical impulses in myelinated neurons are faster and more efficient than in the other types.

What insulates nerve fibers?
Myelin sheaths insulate nerve fibers
What is the fatty tissue that covers axons and speeds up impulses as they travel from cell to cell?
That substance is called the myelin cell or myelin sheath.
The layer of lipid around an axon is called?
Myelin sheath
what is the covering of a fatty material that speeds up the passage of a nerve impulse?
The fatty tissue is called the myelin sheath (or just myelin), the part of the neurone it covers is the axon.
How does a myelin sheath form?
The myelin sheath is an extruded plasma membrane wrapped in a spiral fashion around a nerve axon. The myelin membranes are part of the Schwann cells of the peripheral nervous system.
What is the purpose of myelin sheath?
This is a process that occurs in the CNS and PNS with axons. In the CNS oligodendrocytes surround the axons and in PNS schwann cells surround the axons. the myelin sheath will increase the speed of nervous conduction along the axon.
What insulates nerve fibers?
Myelin sheaths insulate nerve fibers
Does oligodendrocytes serve the same purpose in the central nervous and periphial nervous system?
No, they form myelin sheaths on axons in the CNS while schwann cells form myelin sheaths in the PNS. Hope this answers your question.
What is the purpose of wallerian degeneration?
Degeneration of the axon and myelin sheath distal to the injury site caused by the lack of nutrients.
What purpose does the myelin covering an axon serve?
insulating sheath that speeds up the transmission of impulses along an axon
What is the definition of myelin sheath?
A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron.
It insulates the axon of the neuron?
An insulating layer that surrounds the axon is a myelin sheath.
What increases the speed of the transmission?
Myelin Sheath 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).
How does nicotine affect the myelin production?
Nicotine stimulates CREB phosphorylation which regulates the expression of myelin basic protein and myelin oligodendrocyte glycoprotein.
