1. Neuroglia Notes

2. NEUROGLIA Glia means “glue”
Act in support, guiding development, and stimulation and maintenance

3. TYPES OF NEUROGLIA IN CNS
Astrocytes – star shaped cells with many processes
hold neurons close to blood vessels
help form the blood-brain barrier

5. Oligodendrocyte
most common
form the myelin sheath for neurons of CNS

6. Microglia – small, have fewer processes, and are phagocytes
protect the CNS by phagocytizing microbes and clearing away debris from inflammation and tissue damage

7. Ependymal cells
form the cerebrospinal fluid (CSF) and also assist in its circulation

9. NEUROGLIA OF PNS Schwann cells
supply myelin sheathes to axons in the PNS
Also aids in the regrowth of damaged peripheral axons

10. Satellite cells
flattened cells found around cell bodies of neurons in ganglia
Ganglia = bunched up cell bodies in PNS
