E) Ependymal cells

Question

Quizplus · Accepted Answer

Schwann cells are found wrapped around nerve fibers in the peripheral nervous system (PNS). They form the myelin sheath around axons, allowing for faster transmission of nerve impulses. Oligodendrocytes are the equivalent glial cell in the central nervous system (CNS), but do not wrap around individual axons like Schwann cells. Satellite cells are supportive cells found in ganglia of the PNS. Nodes of Ranvier are gaps in the myelin sheath where axons are exposed. Ependymal cells line the ventricles of the CNS and produce cerebrospinal fluid.
