What are the 2 types of cells in the nervous system?

1. Neurons
2. Neuroglia

2

Name the 6 types of neuroglia in the CNS.

1. Astrocytes
2. Microglia
3. Ependymal cells
4. Oligodendrocytes
5. Satellite cells
6. Schwann cells

3

5 function of astrocytes?

1. Form supportive scaffolding
2. Contact blood vessels to form Blood Brain Barrier
3. Secretes Neuron Growth Factors
4. Communicate electronically with neurons
5. Regulates Extra Cellular Fluid around neurons

4

2 functions of microglia?

1. Phagocytize dead tissue, etc.
2. Gather at sites of damage.

5

2 functions of ependymal cells?

1. Line ventricles of the brain.
2. Makes and moves Cerebral Spinal Fluid

6

Main function of oligodendrocytes?

To make myelin in the CNS

7

Main function of satellite cells?

Unclear, but thought to help nurture and nourish.

8

2 functions of schwann cells?

1. Form myelin sheaths in the PNS.
2. Assist in neural regeneration.

9

Which is the most numerous glial cell?

Astrocytes (90% of glia)

10

What do microglia develop from?

Monocytes

11

Where can you find satellite cells?

Surrounding somas and ganglia in the PNS
