Which One of the Following is NOT Found in the CNS

Question

Which one of the following is NOT found in the CNS?
A) astrocyte
B) microglia
C) ependyma
D) Schwann cell
E) oligodendrocyte

Accepted Answer

Schwann cells are found in the peripheral nervous system (PNS), not in the central nervous system (CNS). The other types of cells listed are all found in the CNS. Astrocytes provide structural and metabolic support to neurons, microglia act as immune cells and remove cellular debris, ependymal cells line the ventricles and produce cerebrospinal fluid, and oligodendrocytes produce myelin for axons in the CNS.
