Neuroglia

Question 1

What are the 4 neuroglia of CNS?

Answer 1

Astrocytes
Oligodendrocytes
Microglial cells
Ependymal

Question 2

What are the two neuroglia of the PNS

Answer 2

Schwann cells

Satellite cells

Question 3

Astrocytes function

Answer 3

Support neurons
Protect neurons from harmful substances
Help Maintain proper chemical environment for generation of nerve impulses
Assist with growth and migration of neurons during development
Play a role in learning and memory
Help form the blood-brain barrier

Question 4

Microglial cells

Answer 4

Protect CNS cells from disease by engulfing invading microbes; migrate to areas of injured nerve tissue where they clear away debris of dead cells

Question 5

Oligodendrocytes function

Answer 5

Produce and maintain myelin sheath around several adjacent axons of CNS neurons

Question 6

Ependymal cells

Answer 6

Line ventricles of the brain and central canal of the spinal cord; form cerebrospinal fluid and assist in its circulation

Question 7

Schwann cells

Answer 7

Produce and maintain myelin sheath around a single axon of a PNS neuron; participate in regeneration of PNS axons

Question 8

Satellite cells

Answer 8

Support neurons in PNS ganglia and regulate exchange of materials between neurons and interstitial fluid
