2. ANS: a.--- oligodendrocytes
Work Step by Step
Insulating coats are laid over nerve fibers in CNS as well as in the CNS. In both cases this function is carried out by supporting cells of the nervous system --neuroglia. In the CNS the melinating neuroglia are called oligodendrocytes. In the peripheral nervous system (PNS), the myelinating cells are called Schwann cells or neurilemma.
