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.
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.
Undulating.
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.

"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.
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.

A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron.

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.
Nicotine stimulates CREB phosphorylation which regulates the expression of myelin basic protein and myelin oligodendrocyte glycoprotein.
The endoneurium surrounds and protects the myelin sheath.
the disease that strips myelin from nerves is meningitis
