Rough Endoplasmic Reticulum. it has a rough surface and is covered in ribosomes.
Answer:
3 and 7
Explanation:
They have the same DNA genomes.
<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)
Answer:
The lens
It helps to focus on objects and light
Answer:
This phenomenon is known by neuroscientists as Neuroplasticity, or brain plasticity
Explanation:
Think of plasticity, Neuroplasticity, or brain plasticity, is the simplest terms, as the ability of parts of the brain to adapt their function or ability to change throughout life.
Structural plasticity - brains ability to change in response to the environment.
Functional plasticity-brains ability to change in response to the activities.
