Myelinating Cells

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
