Webb6 sep. 2024 · Oligodendrocytes generate myelin. Myelin, in turn, forms a protective sheath covering each nerve cell’s axon – the threadlike portion of a cell that transmits electrical signals between cells. Damage to myelin is associated with MS, stroke, brain injuries, and certain forms of dementia such as Alzheimer’s disease.
