| 설명 | 치아의 한 부분을 이르는 말이다. 치아관을 피복하는 회백색 반투명의 단단한 물질이다. 치아는 크게 치아관(crown)과 치근(root)으로 나눌 수가 있다. 치아관이란 구강내로 돌출하고 있는 치아의 부분이며, 치근이란 치아관 아래에 존재하는 치아의 부분을 말한다. 사기질은 치아관을 둘러싸고 있는 아주 단단한 조직으로 우리가 입안으로 직접 관찰할 수가 있는 흰색을 띠는 것이다. 전신에서 가장 단단한 부분으로 굳기 6~7° 이므로 석영과 거의 비슷하다. 사기질소주라고 하는 3~5μm 굵기의 사상체의 집합으로 한 개의 이에 수백만 개의 작은기둥이 있다. 사기질은 한번 마모되거나 녹아 버리면 다시 신생되지 않는다. 잇몸의 내부에 있는 치근부에서는 상아질 표면이 시멘트질로 덮여 있다. 사기질에는 신경이 없으므로 여기에 생긴 충치에는 치통이 없으나, 상아질까지 침범되었을 때 냉수가 스며들면 이가 시리고 치통이 시작된다. 소량의 플루오르화물을 섭취하면 이가 건강해진다고 하지만 과다하면 사기질을 상하게 한다. |

| angle of inclination | <orthopaedics> The angle formed by the meeting of a line drawn through the shaft of the femur with one passing through the long axis of the femoral neck; normally it is about 127 |
| condylar guidance inclination | The angle of inclination of the condylar guidance to an accepted horizontal plane. (05 Mar 2000) |
| crown inclination | <dentistry> A tooth movement in which the root of the tooth is tipped toward cheeks (lips) or toward the lingual (palate) of the mouth. (08 Jan 1998) |
| inclination | <dentistry> The angle of the long axis of a tooth from a particular line of reference, the tilt or tip of a tooth. (08 Jan 1998) |

| Aaron's rod | 1. A rod with one serpent twined around it, thus differing from the caduceus of Mercury, which has two. 2. <botany> A plant with a tall flowering stem; especially. The great mullein, or hag-taper, and the golden-rod. (19 Mar 1998) |
| analyzing rod | A device used with a surveyor to determine the relative positions of parallel surfaces and undercuts when designing removable partial dentures. (05 Mar 2000) |
| basal rod | <microbiology> Rod shaped intracellular organelle lying below the undulating membrane of Trichomonas. Generates active bending associated with local loss of birefringence at the bending zone, probably as a result of conformational change in the longitudinal lamellae. Major protein approximately 90 kD. (10 Nov 1998) |
| Maddox's rod | A glass rod, or a series of parallel glass rod's, that converts the image of a light source into a streak of light perpendicular to the axis of the rod. The position of this streak in relation to the image of the light source seen by the fellow eye indicates the presence and amount of heterophoria. (05 Mar 2000) |
| germinal rod | One of the minute elongated bodies resulting from the repeated division of the oocyst during sporogony. In the case of the malarial parasite, it is the form that is concentrated in the salivary glands and introduced into the blood by the bite of a mosquito; it enters the liver cells (exoerythrocytic cycle), whose progeny, the merozoites, infect the red blood cells to initiate clinical malaria. Synonym: germinal rod, zoite, zygotoblast. Origin: sporo-+ G. Zoon, animal (05 Mar 2000) |
| retinal rod | <ophthalmology, physiology> Major photoreceptor cell of vertebrate retina (about 125 million in a human eye). Columnar cells (about 40m long, 1m diameter) having three distinct regions: a region adjacent to and synapsed with, the neural layer of the retina contains the nucleus and other cytoplasmic organelles, below this is the inner segment, rich in mitochondria, that is connected through a thin neck (in which is located a ciliary body) to the outer segment. The outer segment largely consists of a stack of discs membrane infoldings that are incompletely separated in cones) that are continually replenished near the inner segment and that are shed from the distal end and phagocytosed by the pigmented epithelium. The membranes of the discs are rich in rhodopsin, the pigment that absorbs light. (03 Jul 1999) |
| golden-rod | <botany> A tall herb (Solidago Virga-aurea), bearing yellow flowers in a graceful elongated cluster. The name is common to all the species of the genus Solidago. <botany> Golden-rod tree, a shrub (Bosea Yervamora), a native of the Canary Isles. Source: Websters Dictionary (01 Mar 1998) |
| rod | 1. A straight and slender stick; a wand; hence, any slender bar, as of wood or metal (applied to various purposes). Specifically: An instrument of punishment or correction; figuratively, chastisement. "He that spareth his rod hateth his son." (Prov. Xiii. 24) A kind of sceptor, or badge of office; hence, figuratively, power; authority; tyranny; oppression. "The rod, and bird of peace." . A support for a fishing line; a fish pole. <machinery> A member used in tension, as for sustaining a suspended weight, or in tension and compression, as for transmitting reciprocating motion, etc.; a connecting bar. An instrument for measuring. 2. A measure of length containing sixteen and a half feet; called also perch, and pole. Black rod. <anatomy> Rods and cones, the elongated cells or elements of the sensory layer of the retina, some of which are cylindrical, others somewhat conical. Origin: The same word as rood. See Rood. Source: Websters Dictionary (01 Mar 1998) |
