Because I just KNOW there are slackers that just REFUSE to do what is REQUESTED.
THOSE are the ones we're gunna lose.

"Overview of Myelin Sheath
The myelin sheath is a protective layer that surrounds the axons of many nerve cells. It is composed of lipids (fats) and proteins, providing insulation that enhances the speed and efficiency of electrical signal transmission along the nerves.
Structure and Function
Composition: Myelin is made up of approximately 60-75% lipids and 15-25% proteins. Key proteins include myelin basic protein (MBP) and myelin oligodendrocyte glycoprotein (MOG).
Insulation: The myelin sheath acts like insulation on electrical wires, preventing signal loss and allowing for faster communication between neurons.
Nodes of Ranvier: The myelin sheath is not continuous; it has gaps called nodes of Ranvier. These nodes facilitate a process known as saltatory conduction, where electrical impulses jump from one node to the next, significantly increasing transmission speed.
Production of Myelin
Central Nervous System (CNS): In the CNS, myelin is produced by oligodendrocytes, which can myelinate multiple axons.
Peripheral Nervous System (PNS): In the PNS, Schwann cells create myelin, but each Schwann cell typically myelinates only one segment of an axon.
Importance in Health
Myelin is crucial for proper nervous system function. Damage to the myelin sheath can lead to various neurological disorders, the most notable being multiple sclerosis (MS). In MS, the immune system mistakenly attacks myelin, disrupting communication between the brain and the body.
Other Conditions Affecting Myelin
Acute disseminated encephalomyelitis: A rare immune reaction affecting the CNS.
Guillain-Barré syndrome: An autoimmune disorder that attacks myelin in the PNS.
Transverse myelitis: Inflammation of the spinal cord affecting myelin.
Research is ongoing to find ways to repair or regenerate damaged myelin, which could lead to new treatments for these conditions."
