Demyelination results from issues associated with myelin producing cells. What is an example of a myelin producing cell in the c
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)

How does the human heart interact with gravity
emmainna [20.7K]

Answer:

Many parts of the cardiovascular system (including the heart) are influenced by gravity. On Earth, for example, the veins in our legs work against gravity to get blood back to the heart. Without gravity, however, the heart and blood vessels change – and the longer the flight, the more severe the changes.

Why was introducing foxes ineffective at quelling the rapidly-growingrabbit population
natima [27]

The introduction of foxes in order to control, or even decline, the rapidly growing rabbit population was not effective due to very simple reasons, reproduction rates and available area for living.

The rabbits are reproducing quicker than the foxes, and not just quicker, but in larger numbers with every lither, thus outnumbering the foxes by far, even if each fox manages to kill a rabbit or two each day.

The area available for the rabbits to live and spread out is huge, so they are not limited by a small amount of area where their number will have to stop to grow because of lack of food sources, thus spreading around without any problem, especially because of the lack of competition.
