| 영문 | bone age | 한글 | 뼈나이, 골연령 |
|---|---|---|---|
| 설명 | 생리적 연령의 일종으로 나이를 더함에 따른 뼈의 성숙도를 평가하여 어린이의 전신발육을 판정하는 것이다. 뼈나이 평가에는 손목뼈나 발목뼈의 X선사진을 바탕으로 각 화골중심의 형태나 수를 평가한다. 손목뼈의 화골개수를 세는 방법은 간단해서 그의 수는 난 해를 포함한 연령과 거의 일치하지만 뼈발육의 지속을 가늠할 수 있다. |

| 영문 | bone scan | 한글 | 뼈스캔 |
|---|---|---|---|
| 설명 | 뼈의 무기질은 칼슘과 인산염으로 이루어져 있다. 그래서 뼈에 병터가 있는 경우에는 뼈의 인산염분포나 양이 변화하게 된다. 이것을 이용하여 인산염에다가 방사선을 내보내는 물질을 붙여 환자에게 투여하고 그 물질이 내보내는 방사선을 이용하여 영상을 만들어서 뼈의 전반적인 상태나 병터의 발견에 이용하는 방법을 뼈스캔(bone scan)이라고 한다. |

| 영문 | mandibular bone, mandible | 한글 | 아래턱뼈, 하악골 |
|---|---|---|---|
| 설명 | 얼굴을 구성하는 뼈의 한 종류로써, 흔히 말하는 "턱"을 이루는 뼈를 말한다. 얼굴뼈를 이루는 뼈는 위턱뼈(maxillary bone), 아래뼈(mandibular bone), 눈물뼈(lacrimal bone), 코뼈(nasal bone), 광대뼈(zygomatic bone), 보습뼈(vomer) 등이 있다. |

| 영문 | red bone marrow | 한글 | 적색골수 |
|---|---|---|---|
| 설명 | 분화중의 갈비뼈, 척추뼈나 그 외의 많은 작은 뼈에 있는 활동성 골수이다. 적혈구나 과립백혈구의 생산 장소이다. |

| 영문 | nasal bone | 한글 | 코뼈 |
|---|---|---|---|
| 설명 | 코뿌리의 기초를 이루는 사다리꼴의 얇은 뼈로 좌우 한 쌍의 물렁뼈이며, 정중앙선에서 붙어 있다. 코뼈의 윗모서리는 이마뼈, 아래모서리는 코선반연골, 가쪽모서리는 위턱뼈이마돌기와 접한다. 바깥면은 평활하지만 속안면은 요면을 이루며, 세로로 걸친 벌집뼈신경구는 코뼈구멍으로 연결되어 앞벌집뼈신경과 통한다. |

| basophil substance | The material consisting of granular endoplasmic reticulum and ribosomes that occurs in nerve cell bodies and dendrites. Synonym: basophil substance, basophilic substance, chromophil substance, Nissl bodies, Nissl granules, substantia basophilia, tigroid bodies, tigroid substance. (05 Mar 2000) |
|---|---|
| blood group substance | Blood group-specific substances A and B, solution of complexes of polysaccharides and amino acids that reduces the titre of anti-A and anti-B isoagglutinins in serum from group O persons; used to render group O blood reasonably safe for transfusion into persons of group A, B, or AB, but does not affect any incompatibility that results from various other factors, such as Rh. (05 Mar 2000) |
| vasodepressor substance | An incompletely characterised chemical, apparently produced during liver damage, that tends to decrease vascular pressures and relax arterial walls. (05 Mar 2000) |
| gelatinous substance | The apical part of the posterior horn (dorsal horn; posterior gray column) of the spinal cord's gray matter, composed largely of very small nerve cells; its gelatinous appearance is due to its very low content of myelinated nerve fibres. Synonym: substantia gelatinosa, Rolando's gelatinous substance, Rolando's substance. (05 Mar 2000) |
| glandular substance of prostate | The glandular tissue of the prostate as distinct from the stroma and capsule. Synonym: substantia glandularis prostatae. (05 Mar 2000) |
| Reichstein's substance | One of several steroids; e.g., Reichstein's substance F (cortisone), Reichstein's substance H (corticosterone), Reichstein's substance M (cortisol), Reichstein's substance Q (cortexone), and Reichstein's substance S (cortexolone). Synonym: Reichstein's compound. (05 Mar 2000) |
| released substance | <haematology> A polysaccharide precursor molecule which is used to make the antigens on the surface of human blood cells that are classified in the ABO blood group system. (09 Oct 1997) |
| central and lateral intermediate substance | 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) |
| medullary substance | The lipid material present in the myelin sheath of nerve fibres. Synonym: Schwann's white substance. (05 Mar 2000) |
| reticular substance | A filamentous plasmatic material, beaded with granules, demonstrable by means of vital staining in the immature red blood cells. Synonym: alpha substance, filar mass, filar substance, substantia reticularis, substantia reticulofilamentosa. Synonym: reticular formation. (05 Mar 2000) |
| gray substance | 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) |
| ground substance | The amorphous material in which structural elements occur; in connective tissue, it is composed of proteoglycans, plasma constituents, metabolites, water, and ions present between cells and fibres. Synonym: substantia fundamentalis. (05 Mar 2000) |
| growth substance | <biology, cell biology> Signal molecules that are involved in the control of cell growth and differentiation. (12 Dec 1998) |
| Rolando's gelatinous substance | The apical part of the posterior horn (dorsal horn; posterior gray column) of the spinal cord's gray matter, composed largely of very small nerve cells; its gelatinous appearance is due to its very low content of myelinated nerve fibres. Synonym: substantia gelatinosa, Rolando's gelatinous substance, Rolando's substance. (05 Mar 2000) |
