|---|---|---|---|
| 설명 | 1. 뇌는 두 부분으로 나뉘어져 있다. 대뇌겉질이나 뇌의 중앙부에 위치하는 핵(예를 들면 시상, 시상하부, 바닥핵 등)이 회색질이고 그 외는 백색질이다. 척수의 경우에는 바깥쪽의 하얀부분을 백색질이라 하고, 안쪽의 색깔이 어두운 부분을 회색질이라 한다. 이중 실제적으로 대부분의 신경세포의 돌기 특히 축삭과 말이집으로 구성된 것이 백색질이며, 회색질은 신경세포와 보조하는 세포들이 많은 곳이다. 또한 척수도 백색질과 회색질로 나뉘어 있다. 2. 치아에 점착된 백색 물질로서 세균 및 사상 미생물을 함유한 점액 및 상피세포로 구성된다.  |

| gray matter | The cortex of the brain which contains nerve cell bodies. The gray matter is in contrast to the white matter, the part of the brain that contains myelinated nerve fibres. The gray matter is so named because it in fact appears gray. The white matter is white because that is the colour of myelin, the insulation covering the nerve fibres. In the mysterious affair at styles (1920), agatha christie first quoted the fictional belgian detective hercule poirot in regard to his gray matter: 'this affair must be unravelled from within.' he tapped his forehead. 'these little grey cells. It is up to them as you say over here.' (12 Dec 1998) |

| matter, gray | The cortex of the brain which contains nerve cell bodies. The gray matter is as opposed to the white matter, the part of the brain that contains myelinated nerve fibres. The gray matter is so named because it in fact appears gray.

| pontine gray matter | The massive gray matter filling the basilar pons. The nuclei are of fairly homogeneous architecture and project to the cortex of the contralateral cerebellar hemisphere by way of the middle cerebellar peduncle. Their main afferents come from the entire extent of the cerebral neocortex by way of the longitudinal pontine bundles (corticopontine fibres); thus, the pontine nuclei form a major way-station in the impulse conduction from the cerebral cortex of one hemisphere to the posterior lobe of the opposite cerebellum. Synonym: nuclei pontis, pontine gray matter. (05 Mar 2000) |
| heterotopic gray matter | <radiology> Presence of cortical neurons in an abnormal location secondary to arrest of migrating neuroblasts from ventricular walls to brain surface between 7-24 weeks of gestational age, frequency: 3% of healthy population associated with: agenesis of corpus callosum, aqueductal stenosis, microcephaly, schisencephaly, encephalocele X-ray: single/multiple bilateral subependymal nodules along lateral ventricles Differential diagnosis: subependymal spread of neoplasm, subependymal haemorrhage, vascular malformation, tuberous sclerosis, intraventricular meningioma, neurofibromatosis (12 Dec 1998) |
| gray level also gray value | <microscopy> The brightness of pixels in a digitised video image, commonly expressed in integers ranging from 0 (black) to 255 (white) for an 8-bit digital signal. (05 Aug 1998) |
| matter | <chemistry> The material of the universe. (09 Jan 1998) |
| matter, white | The part of the brain that contains myelinated nerve fibres. The white matter is white because it is the colour of myelin, the insulation covering the nerve fibres. The white matter is as opposed to the gray matter (the cortex of the brain which contains nerve cell bodies). (12 Dec 1998) |
| grey matter | <anatomy> Gray matter, the thinking brain, appears gray because it is composed of numerous nerve cells and blood vessels. The outer layer of the cerebrum - the cerebral cortex and areas deep within the brain - the basal ganglia, are made up of grey matter. See: white matter. (16 Dec 1997) |
| white matter | <anatomy> Brain tissue composed of myelin-coated nerve cell fibres. White matter carries information between the nerve cells in the brain and spinal cord. The inner portion of the cerebrum is composed of white matter. See: grey matter. (13 Nov 1997) |
| white-matter disease | <radiology> Demyelinating (myelinoclastic), destruction of existing myelin, acquired diseases with inflammatory characteristics, includes: MS, PML, encephalomyelitis, also may be due to anoxia, infarct, tumour, radiation dysmyelinating, abnormal myelin formation or maintenance, two groups: primary white-matter diseases: leukodystrophies, involve gray matter: Niemann-Pick, Gaucher, Tay-Sachs (12 Dec 1998) |
| sclerosis of white matter | <radiology> Type of dysmyelinating disease, hereditary, peripheral nervous system unaffected in some disorders Specific diseases: adrenoleukodystrophy, metachromatic leukodystrophy, spongy degeneration (Canavan), globoid cell (Krabbe) leukodystrophy, Alexander disease, Pelizaeus-Merzbacher disease, Cockayne syndrome (12 Dec 1998) |
| anterior gray column | The central gray matter of the spinal cord surrounding the central canal. Synonym: substantia intermedia centralis et lateralis, anterior gray column, Stilling's gelatinous substance, substantia gelatinosa centralis. (05 Mar 2000) |
| central gray substance | In general: the predominantly small-celled gray matter adjoining or surrounding the central canal of the spinal cord and the third and fourth ventricles of the brainstem, in particular: the thick sleeve of gray matter surrounding the cerebral sylvian aqueduct in the midbrain, rostrally continuous with the posterior nucleus of the hypothalamus; in sections stained for myelin it stands out from the adjoining tectum and tegmentum by the poverty of its myelinated fibres. Synonym: substantia grisea centralis. (05 Mar 2000) |
| periaqueductal gray | Central gray matter surrounding the cerebral aqueduct in the mesencephalon. Physiologically it is probably involved in rage reactions, the lordosis reflex, feeding responses, bladder tonus, and pain. (12 Dec 1998) |
| Gray | <radiobiology, unit> The new international system unit (SI unit) of absorbed dose of radiation (Gy), 1 Gy = 1 J kg-1 = 100 rad. (16 Dec 1997) |
| gray cataract | A cataract of gray colour, usually seen in senile, mature, or cortical cataract. (05 Mar 2000) |

Nerve tissue that primarily consists of nerve cell bodies, dendrites, and unmyelinated axons, thus having a gray appearance. In contrast, white matter predominantly contains myelinated nerve fibers.
