aivan3 [116]
<h2>CNS  </h2>

Explanation:

An example of a myelin producing cell in the CNS is oligodendrocyte

  • The major function of oligodendrocytes is the formation of myelin
  • Myelin acts as an insulator of axonal segments and is a prerequisite for the high velocity of nerve conduction
  • Larger axons form thicker myelin
  • During development, oligodendrocytes arise from precursors located in the sub-ventricular zone such as the sub-ventricular zone of the lateral ventricles for the cerebrum or the fourth ventricle for the cerebellum
  • In the spinal cord, oligodendrocytes originate from the ventral regions of the neural tube and in the optic nerve they migrate into the nerve from the third ventricle
  • It is the oligodendrocyte precursor cells which migrate to their destination where they then differentiate into the more mature oligodendrocytes
  • The proliferation of the oligodendrocyte progenitor cells is controlled by a number of growth factors released predominantly from neurons but also from astrocytes such as platelet derived growth factor (PDGF) or fibroblast growth factor (FGF)
