Glial cells and their functions Flashcards
1
Q
Oligodendrocytes
a. Fibrous- white matter
b. Protoplasmic- gray matter
A
Contain multiple cell processes that wrap around the axon on neurons -> forming myelin sheath
2
Q
Astrocytes
A
Many functions: axon guidance, synaptic support, to control blood-brain barrier and blood flow
most abundant in CNS
3
Q
Ependymal Cells
A
Secrete, circulate, and reabsorb CSF (cerebrospinal fluid)
4
Q
Microglia
A
Related to macrophages and antigen- presenting cells;
Phagocytic anti-microbial cells
5
Q
Schwann Cells
A
Myelination of neurons; each Schwann Cell can myelinate only one axon
6
Q
Satellite Cells of ganglia
A
Support, insulate, and nourish the ganglion cells
