Question 1

Astrocytes

Answer 1

Brain, brainstem, & spinal cord - Regulates tissue environment of CNS, determines chemical/nutrient levels (sugars, sodium, etc.); Forms blood-brain barrier

Question 2

Microglial cells

Answer 2

Find & destroy harmful microorganisms

Question 3

Ependymal cells

Answer 3

Line spaces of spinal canal, create cerebral-spinal fluid; Use & alter blood plasma to create the fluid, fills central canal & ventricles

Question 4

Oligodendrocyte

Answer 4

Make myelin – Insulation (mostly lipid), wrap myelin around CNS neuron axons; Helps electrical signals travel efficiently & faster

Question 5

Answer 5

In PNS; surrounds neurons, keeping them alive; play essential roles in the development, maintenance, function, and regeneration of peripheral nerves

Question 6

Satellite cells

Answer 6
