| 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 | 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. |

| plane | 1. To make smooth; to level; to pare off the inequalities of the surface of, as of a board or other piece of wood, by the use of a plane; as, to plane a plank. 2. To efface or remove. "He planed away the names . . . Written on his tables." (Chaucer) 3. Figuratively, to make plain or smooth. "What student came but that you planed her path." (Tennyson) Origin: Cf. F. Planer, L. Planare, fr. Planus. See Plane, Plain, and cf. Planish. <botany> Any tree of the genus Platanus. The Oriental plane (Platanus orientalis) is a native of Asia. It rises with a straight, smooth, branching stem to a great height, with palmated leaves, and long pendulous peduncles, sustaining several heads of small close-sitting flowers. The seeds are downy, and collected into round, rough, hard balls. The Occidental plane (Platanus occidentalis), which grows to a great height, is a native of North America, where it is popularly called sycamore, buttonwood, and buttonball, names also applied to the California species (Platanus racemosa). Origin: F, fr. L. Platanus, Gr, fr. Broad; so called on account of its broad leaves and spreading form. See Place, and cf. Platane, Plantain the tree. Without elevations or depressions; even; level; flat; lying in, or constituting, a plane; as, a plane surface. In science, this word (instead of plain) is almost exclusively used to designate a flat or level surface. Plane angle, the angle included between two straight lines in a plane. Plane chart, Plane curve. See Chart and Curve. Plane figure, a figure all points of which lie in the same plane. If bounded by straight lines it is a rectilinear plane figure, if by curved lines it is a curvilinear plane figure. Plane geometry, that part of geometry which treats of the relations and properties of plane figures. Plane problem, a problem which can be solved geometrically by the aid of the right line and circle only. Plane sailing, a scale for the use of navigators, on which are graduated chords, sines, tangents, secants, rhumbs, geographical miles, etc. Plane surveying, surveying in which the curvature of the earth is disregarded; ordinary field and topographical surveying of tracts of moderate extent. Plane table, an instrument used for plotting the lines of a survey on paper in the field. Plane trigonometry, the branch of trigonometry in which its principles are applied to plane triangles. Origin: L. Planus: cf. F. Plan. See Plan. 1. <geometry> A surface, real or imaginary, in which, if any two points are taken, the straight line which joins them lies wholly in that surface; or a surface, any section of which by a like surface is a straight line; a surface without curvature. 2. <astronomy> An ideal surface, conceived as coinciding with, or containing, some designated astronomical line, circle, or other curve; as, the plane of an orbit; the plane of the ecliptic, or of the equator. 3. <mechanics> A block or plate having a perfectly flat surface, used as a standard of flatness; a surface plate. 4. A tool for smoothing boards or other surfaces of wood, for forming moldings, etc. It consists of a smooth-soled stock, usually of wood, from the under side or face of which projects slightly the steel cutting edge of a chisel, called the iron, which inclines backward, with an apperture in front for the escape of shavings; as, the jack plane; the smoothing plane; the molding plane, etc. <geometry> Objective plane, the plane in which lie both the incident ray and the refracted or reflected ray.
