Question

What is the substance that surrounds, coats, and protects nerve fibers in the brain and spinal cord?

In multiple sclerosis, the immune system destroys
, the substance that coats and protects nerve fibers in the brain and spinal cord. This causes inflammation and injury to the nerves, and the axons don't conduct impulses as well

Answer 1

Step-by-step explanation:

Myelin is a lipid-rich (fatty) substance that surrounds nerve cell axons (the nervous system's "wires") to insulate them and increase the rate at which electrical impulses (called action potentials) are passed along the axon.

Answer 2

Myelin

Step-by-step explanation:

Myelin is a fatty material that coats, protects, and insulates nerves, enabling them to quickly conduct impulses between the brain and different parts of the body. Myelin also contains proteins that can be targeted by the immune system.
