Neuroglia support and protect neurons. The centralnervous system (CNS) has four (4) types of neuroglia. Correctlymatch each cell characteristic with the correct neuroglialcell.
Line the centre canal in spinal cord
Largest neuroglial cell
Can migrate to through neural tissue
Produce, monitor and circulate cerebrospinal fluid
Most abundant neuroglial cells
Maintain blood- brain barrier Â
Many are ciliated
Many cytoplasmic processes with feet
Help to provide structural for framework CNS
Cell type includes ependyocytes and tanycytes
Smallest number of neuroglial cells
Forms cuboidal columnar epithelium
Lacking abasement membrane
Engulf cellular debris, waste products and pathogens
Contain many microfilaments
Adjust composition of interstitial fluid
Have some slender cytoplasmic extensions in contact with neuronsurface
Small cell body
Forms membranous wrapping (myelin) around axon
Provides electrical insulation for axon
Maintain permeability characteristics of capillary endothelialcells
Phagocytes
Repair/ stabilise damaged neural tissue
Cytoplasmic processes each with very fine branches
Increases speed of action potential
