|---|---|---|---|
| 설명 | 상피는 한 층 또는 여러 층의 세포로 이루어진 판 모양의 구조로 신체의 표면과 관상구조의 내강을 둘러싸고 있다. 상피세포와 상피세포사이의 적은 양으로 존재하여 상피사이의 공간을 채우고 있는 세포간질을 합쳐 상피조직이라 한다. 상피조직에는 원칙적으로 혈관이 분포되어 있지 않다. |

| 영문 | granulation tissue | 한글 | 육아조직 |
|---|---|---|---|
| 설명 | 모세혈관이 풍부하며 왕성하게 증식을 계속하는 어린 결합조직. 창상 등 조직 결손에 대한 수복, 이물처리의 기질화, 염증이 만성적인 경과에 있거나 종양증식에 동반된 사이물질의 반응성 염증에서 관찰된다. 구성성분은 생긴지 얼마 안되는 어린 육아조직은 섬유모세포의 증식, 새로 생긴 모세혈관과 여러 유주세포 및 다른 중간엽세포(백혈구, 림프구, 형질세포, 조직구, 단핵구, 거대세포)등으로 구성된다. 이것이 시간이 지나 그리되면, 모세혈관과 유주세로, 다른조직성분을 감소시켜 만성화하여 오래된 육아가 되며 결국은 섬유세포와 아교질섬유로 구성된 반흔조직으로 변한다. |

| 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. |

| Weber's organ | A minute pouch in the prostate opening on the summit of the seminal colliculus, the analogue of the uterus and vagina in the female, being the remains of the fused caudal ends of the paramesonephric ducts. Synonym: utriculus prostaticus, masculine uterus, Morgagni's sinus, sinus pocularis, uterus masculinus, vagina masculina, vesica prostatica, Weber's organ. (05 Mar 2000) |
| multiple organ failure | A progressive condition usually characterised by combined failure of the lungs, liver, kidney, and clotting mechanisms, usually postinjury or postoperative. (12 Dec 1998) |
| Corti's organ | A prominent ridge of highly specialised epithelium in the floor of the cochlear duct overlying the basilar membrane of cochlea, containing one inner row and three outer rows of hair cells, or cells of Corti (the auditory receptor cells innervated by the cochlear nerve) supported by various columnar cells: the pillars of Corti, cells of Hensen, and cells of Claudius; the spiral organ is partly overhung by an awning-like shelf, the tectorial membrane, the free marginal zone of which is covered by a gelatinous substance in which the stereocilia of the outer hair cells are embedded. Synonym: organum spirale, acoustic papilla, Corti's organ. (05 Mar 2000) |
| critical organ | The organ or physiologic system that for a given source of radiation would first reach its legally defined maximum permissible radiation exposure as the dose of radiopharmaceutical is increased; e.g., the kidney is the critical organ when 197Hg-chlormerodrin is given. (05 Mar 2000) |
| ptotic organ | An organ with loose attachments, permitting its displacement. Synonym: floating organ, ptotic organ. (05 Mar 2000) |
| spiral organ | A prominent ridge of highly specialised epithelium in the floor of the cochlear duct overlying the basilar membrane of cochlea, containing one inner row and three outer rows of hair cells, or cells of Corti (the auditory receptor cells innervated by the cochlear nerve) supported by various columnar cells: the pillars of Corti, cells of Hensen, and cells of Claudius; the spiral organ is partly overhung by an awning-like shelf, the tectorial membrane, the free marginal zone of which is covered by a gelatinous substance in which the stereocilia of the outer hair cells are embedded.

| neuromast organ | A structure in fish consisting of a long groove or canal extending along each side of the trunk and tail and branching in the head region; the groove or tube is lined with neuroepithelial cells, some of which are in groups known as neuromasts; its function appears to be the detection of vibrations of low frequency. Synonym: neuromast organ. (05 Mar 2000) |
| neurotendinous organ | <cell biology, physiology> A proprioceptive sensory nerve ending embedded among the fibres of a tendon, often near the musculotendinous junction; it is compressed and activated by any increase of the tendon's tension, caused either by active contraction or passive stretch of the corresponding muscle. Synonym: neurotendinous organ, neurotendinous spindle. (05 Mar 2000) |

| organ | 1. An instrument or medium by which some important action is performed, or an important end accomplished; as, legislatures, courts, armies, taxgatherers, etc, are organs of government. 2. <biology> A natural part or structure in an animal or a plant, capable of performing some special action (termed its function), which is essential to the life or well-being of the whole; as, the heart, lungs, etc, are organs of animals; the root, stem, foliage, etc, are organs of plants. In animals the organs are generally made up of several tissues, one of which usually predominates, and determines the principal function of the organ. Groups of organs constitute a system. See System. 3. A component part performing an essential office in the working of any complex machine; as, the cylinder, valves, crank, etc, are organs of the steam engine. 4. A medium of communication between one person or body and another; as, the secretary of state is the organ of communication between the government and a foreign power; a newspaper is the organ of its editor, or of a party, sect, etc. 5. [Cf. AS. Organ, fr. L. Organum. A wind instrument containing numerous pipes of various dimensions and kinds, which are filled with wind from a bellows, and played upon by means of keys similar to those of a piano, and sometimes by foot keys or pedals; formerly used in the plural, each pipe being considired an organ. "The deep, majestic, solemn organs blow." (Pope) Chaucer used the form orgon as a plural. "The merry orgon . . . That in the church goon [go]" Barrel organ, Choir organ, Great organ, etc. See Barrel, Choir, etc. <anatomy> Cabinet organ, a passage in which the tonic or dominant is sustained continuously by one part, while the other parts move. Origin: L. Organum, Gr.; akin to work, and E. Work: cf. F. Organe. See Work, and cf. Orgue, Orgy. Source: Websters Dictionary (01 Mar 1998) |
