|
Astrocytes |
Forms BBB. Microfilaments for strength. Regulate growth. Maintain chemical environment. Learning and memory. Most abundant neuroglia. Provide nutrient to neurons. Take up excess neurotransmitter and maintain balance of K ions and Ca ions |
|
|
Oligodendrocyte |
Myelin sheath. Smaller, shorter, fewer processes, form supporting network around CNS neurons and produce myelin sheath around several adjacent axons of CNS neurons. |
|
|
Microglia |
Phagocytes. Derives from mesodermal cells into monocytes and macrophages. Protect CNS cells from disease by eating microbes. Migrate to areas of injured nerve tissue to clear debris of dead cells. May also kill healthy cells. |
|
|
Ependymal |
Circulates CSF. Single layer cuboidal to columnar in shape, has microvilli and cilia. Lines ventricle of brain and central canal of spinal cord. Produce CSF and monitor it. |
|
|
Schwann cell |
Neurolemmocytes. Myelin sheath. Encircles axons. Surrounds multiple unmyelinated axons with single layer of its plasma membrane. Produce part of myelin sheath around single axon. |
|
|
Satellite cells |
Exchange material between neuronal cell bodies and IF. Around cell bodies of neuron in PNS ganglia. |
