Which statement about glial cells is true?

C) They are found primarily in skeletal muscle tissue.

Question

Quizplus · Accepted Answer

Glial cells in the central nervous system, specifically microglia, provide immune functions by monitoring for and responding to inflammation and cellular damage.

Note: B is not entirely incorrect, as some glial cells (such as oligodendrocytes) do wrap around neuronal processes to form myelin sheaths. However, not all glial cells are insulated in this way. C, D, and E are all incorrect statements about glial cells.
