WebMyelin is a lipid-rich material 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. The myelinated axon can be likened to an electrical wire (the axon) with insulating material (myelin) around it. Web14 apr. 2024 · April 14, 2024 Myelin is the protective lipid sheath wrapped around a nerve.
