NCI Thesaurus Code: C12477 (see NCI Thesaurus info)
Semantic Type: Cell
NCIt Definition: A heterogeneous group of specialized neuroglial cells with many diverse supporting roles in the structure, function, and homeostasis of the central nervous system.
NCI-GLOSS Definition: A large, star-shaped cell that holds nerve cells in place and helps them develop and work the way they should. An astrocyte is a type of glial cell.
CSP Definition: neuroglial CNS cells of ectodermal origin characterized by fibrous, protoplasmic, or plasmatofibrous processes.
MSH Definition: A class of large neuroglial (macroglial) cells in the central nervous system - the largest and most numerous neuroglial cells in the brain and spinal cord. Astrocytes (from "star" cells) are irregularly shaped with many long processes, including those with "end feet" which form the glial (limiting) membrane and directly and indirectly contribute to the BLOOD-BRAIN BARRIER. They regulate the extracellular ionic and chemical environment, and "reactive astrocytes" (along with MICROGLIA) respond to injury.

|SOS||Serves several functions, such as structural support for nerve cells, proliferation and repair after injury to the nerves, and isolation and grouping of nerve fibers and terminals; their interaction with neurons is of the utmost importance in the development of the CNS.||AOD|
