Microglia

 

mesoglia, small rounded cells in the central nervous system.

Microglia develop from cells of connective tissue and constitute about 10 percent of the total number of cells of the neuroglia. Each microglial cell is connected by branching processes with the neuron-neuroglia system and the brain capillaries. The number and size of the microglial cells increase with infections, intoxications, or brain edema. The cells perform a phagocytic role, removing necrotic sections of nerve tissue.
