Question 3

Neuroglia

Formation of Blood brain barrier

Answer 3

Astrocytes

FIBROUS astrocytes:
* Provide supporting framework
* Electrical insulators
* Limit spread of feetneurotransmitters
* Take up K+ ions
PROTOPLASMIC astrocytes:
* Store glycogen
* Have a phagocytic
* Take place of dead neuron
* Conduit for metabolites or raw perivascular feetmaterials
* Produce trophic substances

Question 4

Neuroglia

Forms myelin sheath in CNS (brain & spinal cord) and their maintenance

Answer 4

Oligodendrocytes

1 Oligodendrocyte can form myelin sheath for about 60 axons in CNS
* Oligodendrocytes also Influence biochemistry of neurons
