Answer:
C) is prevented due to growth-inhibiting proteins of oligodendrocytes
Explanation:
Oligodendrocytes are the neuroglial cell and mainly serve to support neurons. These cells also produce a myelin sheath around axons of neurons of the central nervous system. Axons in the CNS display little regrowth or neurogenesis. Inhibition of regeneration is due to several factors such as the absence of a neurolemma and an inhibitory influence of the oligodendrocytes on axon regrowth. For the purpose, the oligodendrocytes produce growth-inhibiting proteins. Axons in the CNS are myelinated by oligodendrocytes and this myelin is one of the inhibiting factors in the regeneration of neurons.
