Fibrous astrocytes are star-shaped helpers with long, smooth arms. They take care of the brain's wiring.

Fibrous astrocytes are star-shaped glial cells. They live in the white matter, the part of the brain full of long axons, which are like wires.
Their arms are long, thin, and smooth, with fewer little branches than the bushy kind of astrocyte.
Their arms are packed with tiny threads that make them strong, a bit like the cables inside a bridge.
If the brain gets hurt, astrocytes help patch up the spot.
