O are part of the blood-brain barrier.
O are phagocytic cells in the CNS.
O produce cerebrospinal fluid.
O form myelin sheaths.
O are part of the choroids plexus.

Answer 1

Microglia are phagocytic cells in the CNS that play a role in immune surveillance by ingesting and digesting cellular debris and pathogens.

Step-by-step explanation:

Microglia are a type of glial cell found in the central nervous system (CNS) that serve as phagocytic cells. They are associated with immune surveillance in the brain, functioning similarly to macrophages in the rest of the body by ingesting and digesting diseased or damaged cells and pathogens.

Microglia are not involved in producing cerebrospinal fluid, forming myelin sheaths, being part of the blood-brain barrier, or as part of the choroid plexus.
