Myelin is a fatty substance that forms a protective sheath around the axons of neurons in the nervous system. Its primary job is to insulate these axons, which enhances the speed and efficiency of electrical signal transmission between nerve cells. This rapid communication is essential for proper functioning of the nervous system, impacting everything from reflexes to cognitive processes. Additionally, myelin plays a role in maintaining the health of neurons and supporting overall brain function.

What is myelin sheath on nerve fibers?
The endoneurium surrounds and protects the myelin sheath.
Do myelin fibers contain any collagen?
Myelin fibers themselves do not contain collagen. Myelin is primarily composed of lipids and proteins, specifically a type of protein called myelin basic protein and other associated proteins that help in its structure and function. Collagen is a structural protein found in connective tissues, but it is not a component of the myelin sheath surrounding nerve fibers.
Are neurotransmitters found in the myelin shealth?
No, neurotransmitters are not found in the myelin sheath. The myelin sheath is a protective covering that surrounds nerve fibers, while neurotransmitters are chemical messengers that transmit signals between neurons.
What type of cells produce the myelin sheath in the central nervous system?
Oligodendrocytes and Schwann cells both produce myelin. Oligodendrocytes produce myelin in the CNS, whereas Schwann cells produce myelin in the PNS. CNS refers to central nervous system PNS refers to peripheral nervous system
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.

How does nicotine affect the myelin production?
Nicotine stimulates CREB phosphorylation which regulates the expression of myelin basic protein and myelin oligodendrocyte glycoprotein.
What disease strips myelin from nerves?
the disease that strips myelin from nerves is meningitis
What is myelin sheath on nerve fibers?
The endoneurium surrounds and protects the myelin sheath.
What is the function of myelin?
Myelin is the material that covers the spinal cord. It protects the cord from damage. If the myelin wears away, then a person is said to have Multiple Sclerosis.
What is myelin rich in?
Myelin is the material that surrounds and protects the spinal cord, and it helps conduct information signals up and down the cord. Myelin is rich in protein.

What creates myelin sheath?
Oligodendrocytes are specialized neurolgical cells that produce myelin sheath.
