Astrocytes

The stars of the brain

Astrocytes are the most abundant glial cells in the brain, outnumbering neurons. They support neurons in proper function by providing them with nutrients, structural support and by regulating the concentration of neurotransmitters. Their name comes from the Greek word astron meaning star, due to their star-shaped appearance.
