| oligodendroglia | A class of neuroglial (macroglial) cells in the central nervous system. Oligodendroglia may be called interfascicular, perivascular, or perineuronal satellite cells according to their location. The most important recognised function of these cells is the formation of the insulating myelin sheaths of axons in the central nervous system. (12 Dec 1998) |

| oligodendroglioma | <oncology, tumour> May be subdivided into primary brain tumours and the more common, secondary brain tumours. Primary brain tumours (for example astrocytoma, craniopharyngioma, glioma, ependymoma, neuroglioma, oligodendroglioma, glioblastoma multiforme, meningioma, medulloblastoma) arise from the uncontrolled proliferation of cells within the brain. Secondary brain tumours occur from the spread of cancer into the brain from a distant cancerous organ (metastasis). Common symptoms of a brain tumour include headache, nausea, vomiting, seizures, change in mentation, neurologic symptoms and loss of memory. (27 Sep 1997) |

See: 1,4-alpha-d-glucan branching enzyme. Synonym: oligoglucan-branching glycosyltransferase. (05 Mar 2000) |
