Myelin is the fatty, insulating sheath that surrounds some neurons, specifically their axons. It allows electrical impulses to travel faster down nerves.
Here are the cells that make myelin.
- Central nervous system: oligodendrocytes
- Memory aid: o is symmetrical and central-looking, like the cross-section of a stick; dictators wave batons around while giving heinous orders and they’re rather central to autocracy
- Peripheral nervous system: Schwann cells
- Memory aid: s is for side, in reference to the periphery
