mi·cro·gli·a M0273725 (mī′krō-glē′ə, -glī′-)pl.n. Small neuroglial cells of the central nervous system that have long processes and act as phagocytes at sites of neural damage or inflammation, destroying pathogens and damaged cells. mi′cro·gli′al adj.microglia (ˌmaɪkrəʊˈɡlɪə) n (Anatomy) one of the two types of non-nervous tissue (glia) found in the central nervous system, having macrophage activity. Compare macrogliaThesaurusNoun | 1. | microglia - neuroglial tissue of mesodermal origin that can become phagocyticglia, neuroglia - sustentacular tissue that surrounds and supports neurons in the central nervous system; glial and neural cells together compose the tissue of the central nervous systemmicrogliacyte - a cell of the microglia that may become phagocytic and collect waste products of nerve tissue |
Microglia
microglia[mī′kräg·lē·ə] (neuroscience) Small neuroglia cells of the central nervous system having long processes and exhibiting ameboid and phagocytic activity under certain pathologic conditions. 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. microglia
microglia [mi-krog´le-ah] non-neural cells forming part of the adventitial structure of the central nervous system. They are migratory and act as phagocytes of waste products of the nervous system. adj., adj microg´lial.mi·crog·li·a (mī-krog'lē-ă), This word is grammatically singular. Avoid the mispronunciation microgli'a.Small neuroglial cells of the central nervous system, originating in the bone marrow, that may become phagocytic in areas of neural damage or inflammation.
