A bushy star
Astro means star. Astrocytes are star-shaped glial cells, the helper cells of the brain.
Protoplasmic astrocytes live in the gray matter, where most neuron cell bodies are. They have lots of short, bushy branches that fill the space around them.
Wow!
Each one of these astrocytes looks after its own little patch of brain, and they hardly overlap. It is like neighbors each caring for their own yard!
