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)

A mouse geneticist selected for increased 12-day litter weight (total weight of a litter of offspring 12 days after birth) in a
wlad13 [49]

Answer:

12-day litter weight is a trait that has an important genetic influence and therefore also a high response to selection

Explanation:

Heritability is a statistical measure of how much of the variation in a given trait can be attributed to genetic differences and how much of trait variation is due to environmental factors. A heritability value close to 1 indicates that almost all of the variability is due to genetic factors, while being poorly influenced by environmental factors. In this case, 12-day litter weight is a trait that exhibits an important genetic component (i.e., a high heritability value), thereby the correlation between parent and offspring will be high and lines selected for this trait will show a high response to selection.

LenKa [72]

The baglike structure that contains a clear fluid in which the developing embryo floats is called the Amnion.

<h3>What is an Amnion?</h3>

The membrane that  covers the embryos of reptiles, birds, and the mammals when first formed is called Amnion.

It contains amniotic fluid, which serves as an amniotic sac that provides a protective shield for the developing embryo. Together with the amnion, contains the

  • chorion
  • the yolk sac
  • allantois

with different functions to  protect the embryo.

The amniotic sac in humans is enclosed in the uterus while for birds, reptiles ,it is enclosed in a shell.
