Explain how glia function within the nervous system.
vovikov84 [41]

Answer:

In the central nervous system, about 90 percent of the cells are glia. Originally, the glia was considered to be passive cells, that is, which only functions to support the nerve cells physically, thus, the term glia is used, which means glue.  

However, the glia plays an essential function in various homeostatic procedures and also at the time of development. The four prime kinds of glia prevail, that is, oligodendrocytes, astrocytes, microglia, and ependymal cells. The glial cells are also known as the supporting cells of the nervous system.  

The prime functions of glial cells are to provide oxygen and nutrients to the neurons, to envelope neurons and hold them in position, to eradicate and remove the carcasses of the dead neurons, and to insulate one neuron from another.
