Tend to be smaller than neurons but outnumbers neurons (10 to 1) Supply nourishment to neurons, help remove neuron"s waste products, and provide insulation around many axons (myelin sheath) New research suggest that glial cells may also send and receive chemical signals. May play an important role in memory formation. Gradual deterioration of glial tissue might contribute to the emergence of. Some types of glia can detect neural impulses and send signals to other glial cells: neuron. Individual cells in the nervous system that receive, integrate, and transmit information.
