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
