What is the basis for the functional classification of neurons?

Two major cell groups make up the nervous system—neurons and supporting cells such as astrocytes and Schwann cells. Which are 'nervous' cells? Why? What are the major functions of the other cell group?

Phagocytic cells in nervous tissue of the CNS are (a) astrocytes, (b) ependymal cells, (c) oligodendrocytes, (d) microglia.
