| 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. |

| glandulopreputial lamella | A layer of embryonic epithelial tissue that gives rise to the prepuce. (05 Mar 2000) |
| vitreous lamella | The transparent, nearly structureless inner layer of the choroid in contact with the pigmented layer of the retina. Synonym: basal lamina of choroid, basal layer of choroid, Bruch's membrane, Henle's membrane, lamina vitrea, vitreous lamella, vitreous membrane. (05 Mar 2000) |
| ribosome-lamella complex | A cylindrical cytoplasmic inclusion composed of concentrically arranged sheets of membranes alternating with rows of ribosomes; characteristic of the hairy cell in leukaemic reticuloendotheliosis. (05 Mar 2000) |
| ground lamella | One of the lamellae of partially resorbed osteons occurring between newer, complete osteons. Synonym: ground lamella, intermediary system, intermediate lamella. (05 Mar 2000) |
| middle lamella | First part of the plant cell wall to be formed, laid down in the phragmoplast during cell division as the cell plate. Subsequently makes up the central part of the double cell wall that separates two adjacent cells, cementing together the two primary walls. Rich in pectin and relatively poor in cellulose.

| circumferential lamella | A bony lamella that encircles the outer or inner surface of a bone. (05 Mar 2000) |
| concentric lamella | One of the concentric tubular layers of bone surrounding the central canal in an osteon. Synonym: haversian lamella. (05 Mar 2000) |
| cornoid lamella | A narrow vertical column of parakeratosis in the epidermal stratum corneum; characteristic of porokeratosis. (05 Mar 2000) |

| interstitial lamella | One of the lamellae of partially resorbed osteons occurring between newer, complete osteons. Synonym: ground lamella, intermediary system, intermediate lamella. (05 Mar 2000) |
| elastic lamella | A thin sheet or membrane composed of elastic fibres; distinguished from elastic membrane, which usually refers to a condensed mass of fibres, as in an artery, whereas an elastic lamella may be a looser elastic layer such as found in a vein or the respiratory tract. (05 Mar 2000) |
| triangular lamella | A double fold of pia mater, enclosing subarachnoid trabeculae, between the fornix above and the epithelial roof of the third ventricle and the thalami below; at each lateral margin is a vascular fringe projecting into the choroidal fissure of the lateral ventricle; on its undersurface are several small vascular projections filling the folds of the ependymal roof of the third ventricle. Synonym: tela choroidea ventriculi tertii, tela choroidea superior, triangular lamella, velum interpositum, velum triangulare. (05 Mar 2000) |
| lamella | A thin, plate-like layer, middle lamella, the layer between the walls of two adjacent plant cells. (09 Oct 1997) |
