| 영문 | tissue | 한글 | 조직 |
|---|---|---|---|
| 설명 | 특정 구조와 기능을 갖는 세포 집단. 세포 사이에는 다소간 세포간질이 들어 있다. 세포간질에는 글리코사미노글리칸, 히드록시아파타이트와 같은 기질과 아교질섬유와 같은 섬유가 발견된다. 조직성상은 구성세포와 세포간질의 종류와 양에 의해 결정된다. 조직은 상피조직, 지지조직, 근육조직, 신경조직으로 대별되며, 상피조직은 세포간질을 거의 갖지 않으며, 지지조직은 결합조직이나 뼈조직과 같이 세포간질이 풍부한 것이 많다. |

| 영문 | tissue biopsy | 한글 | 조직생검 |
|---|---|---|---|
| 설명 | 환자의 병적인 조직의 일부를 떼어 내서 병리조직표본을 만들어서 현미경적으로 검사하는 것. 외과적 수술재료로부터 병리조직학적 검사를 하여 생체내의 병변을 추구하는 분야를 외과병리학이라고 한다. 생검에는 쐐기생검, 천자침생검, 꿰뚫기식생검, 내시경생검 외에 세포진이라고 불리우는 박리세포진이나 세척세포진 등 떨어진 세포를 도말검사하는 방법이 포함된다. |

| 영문 | target tissue | 한글 | 표적조직 |
|---|---|---|---|
| 설명 | 호르몬에 대하여 표적이 되는 세포라는 의미로서 그 호르몬에 대한 수용체를 가지고 있는 세포. 예를 들어 인슐린은 인슐린 수용체를 가진 세포를 표적세포로 하여 이 세포에만 작용한다. |

| 영문 | subcutaneous tissue, subcutis | 한글 | 피하조직 |
|---|---|---|---|
| 설명 | 피부에서 진피의 아랫부분을 말함. 여기에는 지방조직이 많다. 기능은 열의 격리, 충격흡수, 영양저장소 등이다. |

| cancellous tissue | Latticelike or spongy osseous tissue. (05 Mar 2000) |

| cardiac muscle tissue | See: cardiac muscle. (05 Mar 2000) |
| Gamgee tissue | A thick layer of absorbent cotton between two layers of absorbent gauze, used in surgical dressings. (05 Mar 2000) |
| gelatinous tissue | A type of connective tissue little differentiated beyond the mesenchymal stage; its ground substance of glycoproteins is abundant and contains fine collagenous fibres and fibroblasts; in its most characteristic form, it appears in the umbilical cord as Wharton's jelly. Synonym: gelatinous tissue. (05 Mar 2000) |
| Verhoeff's elastic tissue stain | <technique> A stain for tissue sections in which a mixture of haematoxylin, ferric chloride, and Lugol's iodine solution is used; tissue may be counterstained, if desired, with eosin or van Gieson's stain; elastic fibres and nuclei appear blue-black to black while collagen and other components are shades of pink to red. (05 Mar 2000) |
| cartilaginous tissue | See: cartilage. (05 Mar 2000) |
| cavernous tissue | A tissue with numerous vascular spaces that may become engorged with blood. Synonym: cavernous tissue. (05 Mar 2000) |
| reticular tissue | Retiform tissue, a tissue in which the argyrophilic collagenous fibres form a network and that usually has a network of reticular cells associated with the fibres. (05 Mar 2000) |
| periapical tissue | Tissue surrounding the apex of a tooth, including the apical portion of the periodontal membrane and alveolar bone. (12 Dec 1998) |
| granulation tissue | Highly vascularised tissue that replaces the initial fibrin clot in a wound. Vascularisation is by ingrowth of capillary endothelium from the surrounding vasculature. The tissue is also rich in fibroblasts (that will eventually produce the fibrous tissue) and leucocytes. (18 Nov 1997) |
| granule cell of connective tissue | <cell biology, immunology> Resident cell of connective tissue that contains many granules rich in histamine and heparan sulphate. Release of histamine from mast cells is responsible for the immediate reddening of the skin in a weal and flare response. Very similar to basophils and possibly derived from the same stem cells. Two types of mast cells are now recognised, those from connective tissue and a distinct set of mucosal mast cells, the activities of the latter are T-cell dependent. (05 Jan 1998) |
| mesenchymal tissue | Embryonic connective tissue. See: mesenchyme. (05 Mar 2000) |
| peripheral lymphoid tissue | Secondary lymphoid tissue, not necessarily located peripherally. See: lymphoid tissue. (18 Nov 1997) |
| mesonephric tissue | Intermediate mesoderm situated in the thoracic and lumbar regions of the embryo or foetus; it evolves into the mesonephros and associated structures. (05 Mar 2000) |
| metanephrogenic tissue | Tissue derived from the intermediate mesoderm caudal to mesonephric levels and concerned with the formation of the nephrons of the metanephros. (05 Mar 2000) |
