Detailed explanation-1: -A myelin sheath is a sleeve (sheath) that’s wrapped around each nerve cell (neurons). It’s a protective layer of fat (lipids) and protein that coats the main “body” section of a neuron called the axon.
Detailed explanation-2: -Myelin and Your Nerves The myelin sheath wraps around the fibers that are the long threadlike part of a nerve cell. The sheath protects these fibers, known as axons, a lot like the insulation around an electrical wire.
Detailed explanation-3: -Most of the axons in the central nervous system are wrapped in myelin, a substance rich in lipids (fatty substances) and proteins. Like the coating around an electrical wire, myelin insulates and protects the axon and helps speed nerve transmission.
