Question

Quizplus · Accepted Answer

Microglia are the smallest neuroglia of the central nervous system and act as phagocytes, meaning they engulf and digest cellular debris, pathogens, and dead or dying cells. Astrocytes are another type of neuroglia that play a role in maintaining the environment around neurons, but they do not act as phagocytes. Ependymal cells are responsible for producing and circulating cerebrospinal fluid, and oligodendrocytes produce myelin to insulate axons.
