Final answer:
Microglia can be distinguished by Nissl stain histologically.
Step-by-step explanation:
Microglia are a type of glial cell in the central nervous system that serve as the resident component of the immune system. They have properties similar to macrophages, which are white blood cells that ingest and digest diseased or damaged cells in the body.
