cells that regulate concentrations of chemicals that affect neuron signaling and perform other important functions in the brain.
Non-neuronal cells of the nervous system that perform supportive functions.
l cells or glia: support cells in the brain; There are about ten times as many glial cells as neurons in the brain. Little attention has been paid to them, but now researchers are beginning to think they are more important than realized. The name is derived from the Latin word for 'glue'. The most common glia are astrocytes; other glia in the brain are oligodendroglia.
Greek = glue, hence, an adhesive connective tissue.
