| 설명 | 소화관 중에서 위로부터 계속되는 가늘고 긴 관. 작은창자와 큰창자로 대별된다. 포유류에서는 작은창자는 다시 샘창자-빈창자-돌창자로 구별되고 큰 창자는 막창자-잘룩창자-곧창자-항문관으로 나뉜다. 사람의 작은창자는 길이가 6~7m이며, 위 속에서 암죽같이 된 음식물이 간에서 분비되는 쓸개즙, 이자에서 나오는 이자액, 창자벽에서 나오는 창자액 등의 소화액에 의해 소화시켜 흡수한다 작은창자 중 샘창자는 창자사이막이 없고, 복강 후벽에 유착되어 있으며, 전면만 복막에 덮여 있다. 빈창자와 돌창자는 창자사이막이 있다. 그 때문에 빈창자와 돌창자는 이동성이 매우 풍부하다. 작은창자의 내면은 전체에 걸쳐 융모라고 하는 비로드 모양의 점막소돌기가 나있다. 이 때문에 작은창자 내면의 흡수 면적은 넓어 그 총면적은 43m2에 달한다. 쓸개즙-이자액은 각각 온쓸개관과 이자관에 의하여 샘창자로 주입된다. 창자액은 샘창자샘과 창자샘에 의해 분비된다. 큰창자는 전체적으로 굵고 길이는 약 1.5m이다. 주로 수분을 흡수하며, 식물섬유 등 음식물의 일부가 소화된다. 돌창자에서 막창자로 이행하는 부분에 있는 돌막창자판막은 큰창자의 내용물이 작은창자로 역류하는 것을 막는 일을 한다. 잘룩창자는 오름-가로-내림창자의 3부분이 배안을 마치 액자처럼 둘러싸는 위치에 있으며, 오름과 내림창자는 복강후벽에 유착하고, 전면만이 복막으로 덮여 있다. 가로창자는 구불창자가 되어 소골반강으로 들어가 곧창자로 이어진다. 곧창자는 항문관을 거쳐 항문에 열리고 있다. 큰창자의 내면에는 작은창자와 같은 융모는 없다. 점막에는 점액을 분비하는 체세포가 많아 이것은 큰창자에서 점차 고형화하는 변괴을 원활하게 수송하는데 도움이 된다. 창자의 활동은 미주신경과 교감신경으로 된 자율신경에 의해 조절된다. |

| 설명 | 사람의 소화기관은 여러 가지 기관으로 구성되어 있는데, 이중 창자관계는 식도, 위, 작은창자와 큰창자로 구성되어 있다. 입으로 먹어서 잘게 분해된 음식은 식도를 거쳐, 위에서 단백질 등이 소화되고, 샘창자에서 이자에서 분비된 소화효소에 의해 소화, 일부 흡수된 후, 대부분의 영양분은 작은창자에서 흡수된다. 큰창자는 주로 물과 미량원소, 전해질의 흡수에 이용되며, 작은창자에서 내려온 분비물을 저장해 두었다가 큰창자를 거쳐 항문으로 대변을 배설하게 된다. 큰창자는 그 위치에 따라 3부분으로 구성되어지며, 막창자, 잘룩창자 그리고 곧창자이다. 잘룩창자은 다시 오름창자, 가로창자, 내림창자로 이루어져 있으며, 이것은 구불창자란 말은 S자 모양으로 굽어져 있다는 말이다)으로 이어져 곧창자장을 거쳐 항문으로 연결된다. |

| carcinoma, non-small-cell lung | A heterogeneous aggregate of at least three distinct histological types of lung cancer, including squamous cell carcinoma, adenocarcinoma, and large cell carcinoma. They are dealt with collectively because of the shared properties of poor response to conventional chemotherapy and the potential for cure with surgical resection in a fraction of patients. (12 Dec 1998) |
| carcinoma, small cell | An anaplastic, highly malignant, and usually bronchogenic carcinoma composed of small ovoid cells with scanty neoplasm. It is characterised by a dominant, deeply basophilic nucleus, and absent or indistinct nucleoli. There are admixtures of small cell lung carcinoma with other types of lung cancer. Small cell carcinomas are distinguished by their distinctive biological features, response to chemotherapy and radiotherapy, and by their nearly universal tendency to develop overt or subclinical metastases, which frequently eliminates surgery in most patients.

| ribonucleoproteins, small nuclear | Highly conserved nuclear RNA-protein complexes that function in RNA processing in the nucleus, including pre-mRNA splicing and pre-mRNA 3'-end processing in the nucleoplasm. The u3 snrnp is localised in the nucleolus, where it aligns into base pairs with the 28s rrna precursor in a still unidentified region and functions in pre-rrna processing. The u7 snrnp aligns into base pairs with a conserved sequence in the 3'-end of histone pre-mRNA and is an essential cofactor for the cleavage that creates the mature nonadenylated 3'-end. (12 Dec 1998) |
| ribonucleoproteins, small, u1 | A nuclear RNA-protein complex that plays a role in RNA processing. In the nucleoplasm, the u1 snrnp along with other small ribonucleoproteins (u2, u4-u6, and u5) assemble into spliceosomes that remove introns from pre-mRNA by splicing. The u1 snrnp base pairs with conserved sequence motifs at the 5'-splice site and recognises both the 5'- and 3'-splice sites and may have a fundamental role in aligning the two sites for the splicing reaction. (12 Dec 1998) |
| ribonucleoproteins, small, u2 | A nuclear RNA-protein complex that plays a role in RNA processing. In the nucleoplasm, the u2 snrnp along with other small ribonucleoproteins (u1, u4-u6, and u5) assemble into spliceosomes that remove introns from pre-mRNA by splicing. The u2 snrnp base pairs with conserved sequence motifs at the branch point, which associates with a heat- and rnaase-sensitive factor in an early step of splicing. (12 Dec 1998) |
| ribonucleoproteins, small, u4-u6 | A nuclear RNA-protein complex that plays a role in RNA processing. In the nucleoplasm, the u4-u6 snrnp along with the u5 snrnp preassemble into a single 25s particle that binds to the u1 and u2 snrnps and the substrate to form mature spliceosomes. There is also evidence for the existence of individual u4 or u6 snrnps in addition to their organization as a u4-u6 snrnp. (12 Dec 1998) |
| ribonucleoproteins, small, u5 | A nuclear RNA-protein complex that plays a role in RNA processing. In the nucleoplasm, the u5 snrnp along with u4-u6 snrnp preassemble into a single 25s particle that binds to the u1 and u2 snrnps and the substrate to form mature spliceosomes. (12 Dec 1998) |
| RNA, small nuclear | Short chains of RNA found in the nucleus. Their function is to remove the introns (nontranslated intervening sequences) from mRNA precursors, thereby bringing the two exons (coding segments) together into correct juxtaposition for enzymatic splicing at the correct point. The resulting mRNA is now ready to leave the nucleus. (12 Dec 1998) |
| sarcoma, small cell | A sarcoma characterised by the presence of small cells, cells measuring 9-14 micrometers with a faint or indistinct rim of cytoplasm and an oval-to-elongated nucleus with relatively dense chromatin. (12 Dec 1998) |
| proximal small bowel disease | <radiology> Giardia, eosinophilic gastroenteritis, Zollinger-Ellison (12 Dec 1998) |

Great and small,of all ranks or degrees; used especially of persons. "His quests, great and small." . Small arms, muskets, rifles, pistols, etc, in distinction from cannon. Small beer. See Beer. Small coal. Little coals of wood formerly used to light fires. Coal about the size of a hazelnut, separated from the coarser parts by screening. Small craft, various small textile articles, as tapes, braid, tringe, and the like. Origin: OE. Small, AS. Sm$l; akin to D. Smal narrow, OS. & OHG. Smal small, G. Schmal narrow, Dan. & Sw. Smal, Goth. Smals small, Icel. Smali smal cattle, sheep, or goats; cf. Gr. A sheep or goat. Source: Websters Dictionary (01 Mar 1998) |
| small-area analysis | A method of analyzing the variation in utilization of health care in small geographic or demographic areas. It often studies, for example, the usage rates for a given service or procedure in several small areas, documenting the variation among the areas. By comparing high- and low-use areas, the analysis attempts to determine whether there is a pattern to such use and to identify variables that are associated with and contribute to the variation.
