Question

answer questions 1-5 with a brief explanation.

1. Henry is interested in a study that shows a rat having a slower than normal reactions due to a lack in glial cells that maintain an axons myelin sheath, which is key in the rate of action potential down that axon. What cells are deficient in this rat if the glial cell was part of the peripheral nervous system?

1. Schwann cells
2. Oligodendrocytes
3. Microglia
4. Astrocytes

2. The space between the arachnoid matter and the dura matter is called ____.
3. What structure contains denticulate ligaments that prevent side to side and inferior motion of the spinal chord?

1. Subarachnoid space
2. Dura matter
3. Arachnoid matter
4. Pia matter

4. What cells are responsible for the breakdown of waste products and pathogens in the central nervous system (CNS)?

1. Microglia
2. Astrocytes
3. Ependymal
4. Oligodendrocytes

5. Which number represents the neuronal structure used to transmit faster signals to other neurons?

1. 6
2. 4
3. 7
4. 5
5. 2
6. 3
7. 1

Answer 1

------->Answer : Oligodendrocytes

The glial cells that maintains the axons of the myelin sheath are oligodendrocytes . So rat have slow reactions than the normal

-------> Answer : sub-dural space

Space between the arachnoid matter and the dura matter is sub-dural space

--------> answer :

Pia matter contains denticulate ligaments that prevent side to side and inferior motion of spin cord

--------> Answer

Microglial cells are responsible for the breakdown of waste products and pathogen
