Introducing - Resting Microglia and Active “Hungry” Microglia!
Microglia are a type of glial cell. They can communicate with other glial cells, neurons and immune cells. In the resting form they have extensive branches to monitor their environment and if they detect signs of danger they transform into the active form. In the active form they have decreased branches, move around to injury sites, and eat cell debris!
Interesting fact: Each microglia seems to occupy a defined territory
