WebJul 6, 2024 · The myelin helps assemble this nodal molecular organization. What is the role of myelin sheath in the transmission? Myelin is an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord. This myelin sheath allows electrical impulses to transmit quickly and efficiently along the nerve cells. Myelin 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. However, unlike the plastic covering on an electrical wire, m…
