Question 3

<p>Describe Astrocytes</p>

Answer 3

<p>'star-cells'

| Support the CNS by maintaining the blood-brain-barrier to regulate the environmental homeostasis of the CNS</p>

Question 4

<p>Describe Oligodendrocytes</p>

Answer 4

<p>Myelin producing cells of the CNS, have multiple dendrites to myelinate numerous axons (Same role as Schwann cells in the PNS, but these only do one axon each)
