E)oligodendrocyte.

Question

Quizplus · Accepted Answer

Oligodendrocytes are glial cells in the CNS that produce and maintain myelin sheaths around axons, providing insulation to allow for more efficient neural signaling. Astrocytes play important roles in regulating the chemical environment surrounding neurons, ependymal cells produce cerebrospinal fluid, neurolemmocytes (also known as Schwann cells) myelinate axons in the PNS, and microglial cells are involved in the immune response within the CNS.
