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.
[micro- + G. glia, glue]

microglia

/mi·crog·lia/ (mi-krog´le-ah) small nonneural cells forming part of the supporting structure of the central nervous system. They are migratory and act as phagocytes to waste products of nerve tissue.microg´lial

microglia

(mī′krō-glē′ə, -glī′-)
n.
(used with a pl. verb) Any of the small neuroglial cells of the central nervous system having long processes and amoeboid and phagocytic activity at sites of neural damage or inflammation.

microglia

[mīkrog′lē·ə]
Etymology: Gk, mikros + glia, glue
small, migratory interstitial cells that form part of the central nervous system. They have various forms and slender, branched processes. Microglia serve as phagocytes that collect waste products of the nerve tissue of the body. Also called Hortega cells, mesoglia.

Microglia

microglial cell

A perivascular bone-marrow-derived cell native to the CNS, belonging to the mononuclear phagocytic system (e.g., monocytes, macrophages, dendritic cells and granulocytes), which presents antigens in an MHC-class-II restricted context.

mi·crog·li·a

(mī-krog'lē-ă)
Small neuroglial cells, possibly of mesodermal origin, which may become phagocytic, in areas of neural damage or inflammation.
Synonym(s): Hortega cells.

microglia

(mi-krog'le-a) [? + glia, glue]
Cells of the central nervous system (CNS) present between neurons or next to capillaries. These cells may function as macrophages when they migrate to damaged CNS tissue.
