Neuroglia Flashcards
1
Q
Neuroglia or glia cells
A
different types of support cells
2
Q
Astrocytes
A
-look like stars because of shape
-provide neurons with oxygen and nutrients
-remove waste
-manage ion concentration around neuron
-help bbb by making capillaries less porous
3
Q
Oligodendrocytes
A
-wrap around CNS neurons to create myelin
-insulating buffer
4
Q
Microglia
A
-protect CNS neurons
-Microglia are macrophages that phagocytize (engulf) cell debris and pathogens
5
Q
Ependymal cells
A
-have cilia
-found in brain cavities with fluid
-remove waste from brain
-have a role in cerebrospinal fluid balance
6
Q
2 Types of Glia cells in PNS:
A
- Schwann cells: provide the protective myelin sheath on axon
- Satellite cells: help protect and support cell bodies that are clustered in groups called ganglia
