Neuroglia support and protect neurons. The central nervous system (CNS) has four (4) types of neuroglia. Correctly match each cell characteristic with the correct neuroglial cell.

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  

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 neuron surface

Small cell body

Forms membranous wrapping (myelin) around axon

Provides electrical insulation for axon

Maintain permeability characteristics of capillary endothelial cells

Phagocytes

Repair/ stabilise damaged neural tissue

Cytoplasmic processes each with very fine branches

Increases speed of action potential

Ependymal cells                 Astrocytes oligodendrocytes microglia

1.The central nervous system (CNS) is composed of billions of discrete cells that are not directly connected but are instead connected by synapses, which require neurotransmitters to pass a signal between cells. Why is this an advantage over a CNS in which all the cells are directly connected? That is, what do we gain by having our brains made up of individual cells that don’t automatically fire an action potential when they are stimulated? What are the drawbacks of the...
