Myelin is a fatty substance that forms a protective sheath around nerve fibers. It acts as insulation, allowing for faster transmission of electrical signals along the nerve cells. Damage to myelin can result in neurological disorders such as multiple sclerosis.

What best describes the waxy-appearing material called myelin?
Myelin is a fatty substance that forms a protective sheath around nerve fibers, helping to increase the speed and efficiency of nerve signal transmission. It is produced by specialized cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Its waxy appearance comes from its high lipid content.
What word best describes a wave?
Undulating.
The speed at which a neural impulse travels is increased when the axon is encased by an?
insulating layer called myelin sheath. This myelin sheath helps to speed up the conduction of electrical impulses along the axon by allowing the impulse to jump between nodes of Ranvier, known as saltatory conduction.
What term best describes light?
Electromagnetic radiation.
What term best describes the phrase something that happens?
"Event" is a term that best describes the phrase "something that happens" as it denotes a happening or occurrence at a specific point in time.
What insulates nerve fibers?
Myelin insulation insulates nerve fibers by wrapping around them and forming a protective sheath. This myelin sheath helps to increase the speed of nerve impulse conduction along the nerve fibers.

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.
What increases the speed of the transmission?
Myelin Sheath Myelin Sheath
What best describes how MS stops action potential propagation?
Without myelin, the internode membrane resistance decreases, preventing local currents from reaching adjacent nodes. Myelin increases the membrane resistance of the axon section it surrounds, allowing local currents to travel between nodes, even though they are 1-2 mm apart. Removing myelin decreases the membrane resistance of internode regions. This shortens the distance that local currents travel because more charge now exits at the internode regions before it reaches the next node.

How does nicotine affect the myelin production?
Nicotine stimulates CREB phosphorylation which regulates the expression of myelin basic protein and myelin oligodendrocyte glycoprotein.
What is myelin sheath on nerve fibers?
The endoneurium surrounds and protects the myelin sheath.
What disease strips myelin from nerves?
the disease that strips myelin from nerves is meningitis
