which of the following types of glial cells produces the myelin sheaths that insulate axons, or nerve fibers, in the central nervous system (cns)?
Oligodendrocytes are cells that coat axons in the central nervous system (CNS) with their cell membrane, forming a specialized membrane differentiation called myelin, producing the so-called myelin sheath. The myelin sheath provides insulation to the axon that allows electrical signals to propagate more efficiently.
