| 영문 | smooth muscle | 한글 | 민무늬근육, 평활근육 |
|---|---|---|---|
| 설명 | 근육 중에서 가로무늬가 없는 근. 가로무늬근에 대응되는 말이다. 척추동물에서는 심장근 이외의 내장근은 모두가 민무늬근이다. 많은 내장장기의 벽에 분포되어 있으며, 대개 돌림층과 세로층의 두 층으로 배열되어 있다. 소화관이나 요관 같은 관모양의 구조에서는 꿈틀운동을 일으켜 내용물이 아래로 내려가게 하는 작용을 한다. 항문관, 위, 요도 등에서는 돌림층의 근육이 특히 두꺼워져 내용물이 내려가는 것을 조절하는 조임근육이 형성되어 있다. 혈관에는 돌림층만 있으며, 혈관을 수축하여 혈액을 쥐어짜는 작용을 한다. 또한 자율신경의 지배를 받으며, 우리의 의지와 관계없이 작용한다. |

| 영문 | voluntary muscle | 한글 | 수의근 |
|---|---|---|---|
| 설명 | 의지의 힘으로 움직일 수 있는 근육. 골격근 외에 피부 내의 피근, 관절주머니에 부착하고 있는 관절근 등이 여기에 속한다. 수의근의 근섬유에는 가로무늬가 있으므로 가로무늬근이라고도 하나, 심장근은 가로 무늬가 있어도 수의근이 아니므로 수의근과 가로무늬근은 동의어는 아니다. 수의근의 운동은 민무늬근보다 빠르다. 수의근이라 해도 골격근 등은 근육무리로서 움직일 수 있으나, 개개의 근육은 따로따로 마음대로 움직이게 할 수 없다. 귓바퀴근육은 사람의 경우 발육이 나빠 마음대로 움직이게 하기 어렵다. |

|---|---|---|---|
| 설명 | 얼굴의 피부를 움직이고 이에 부착되어 있는 얼굴신경의 공급을 받는 수많은 근육을 포함하는 얼굴표정근이나 모방근. |

| cross contamination | <dentistry> Passing bacteria or viruses indirectly from one patient to another through the use of improper sterilisation procedures, unclean instruments, or recycling of products. (08 Jan 1998) |

| cross-cultural comparison | Comparison of various psychological, sociological, or cultural factors in order to assess the similarities or diversities occurring in two or more different cultures or societies. (12 Dec 1998) |
| cross-cultural psychiatry | A field of psychiatry with interest in the study of psychological and psychiatric phenomena as differentially expressed in the cultures of different countries. (05 Mar 2000) |
| cross-cut bur | A bur with blades located at right angles to its long axis. (05 Mar 2000) |
| cross-dressing | Clothing oneself in the clothes of the opposite sex. See: transvestism. (05 Mar 2000) |
| cross-eye | Alternative spelling for crossed eyes. (05 Mar 2000) |
| cross flap | A skin flap transferred from one part of the body to a corresponding part, as from one arm to the other. (05 Mar 2000) |
| cross-hybridisation | <molecular biology> The hydrogen bonding of asingle-stranded DNA sequence that is partially but not entirely complementary to a single-stranded substrate. Often, this involves hybridising a DNA probe for a specific DNA sequence to the homologous sequences of different species. (09 Oct 1997) |
| cross hybridization | Annealing of a DNA probe to an imperfectly matching DNA molecule. (05 Mar 2000) |
| cross infection | <microbiology> Infection transmitted between individuals infected with different pathogenic microorganisms. Any infection which a patient contracts in a health-care institution. (12 Dec 1998) |
| cross-link | A covalent linkage between two polymers or between two different regions of the same polymer. (05 Mar 2000) |
| cross linking | 1. <chemistry> The linking of the chains of a polymer to one another so that the polymer, as a network, becomes stronger and more resistant to being dissolved. 2. <molecular biology> The abnormal linking of two strands of DNA by covalent bonds (as opposed to the normal hydrogen bonds between base pairs), which can occur by exposure to X-rays. Such linking is a type of damage to the DNA molecule and must be repaired before the DNA can replicate and function properly again. (09 Oct 1997) |
| cross-linking reagent | <chemistry> Reagents with two reactive groups, usually at opposite ends of the molecule, that are capable of reacting with and thereby forming bridges between side chains of amino acids in proteins; the locations of naturally reactive areas within proteins can thereby be identified; may also be used for other macromolecules, like glycoproteins, nucleic acids, or other. (12 Dec 1998) |
| cross-matching | 1. A test for incompatibility between donor and recipient blood, carried out prior to transfusion to avoid potentially lethal haemolytic reactions between the donor's red blood cells and antibodies in the recipient's plasma, or the reverse; performed by mixing a sample of red blood cells of the donor with plasma of the recipient (major crossmatch) and the red blood cells of the recipient with the plasma of the donor (minor crossmatch). Incompatibility is indicated by clumping of red blood cells and contraindicates use of the donor's blood. 2. In allotransplantation of solid organs (e.g., kidney), a test for identification of antibody in the serum of potential allograft recipients which reacts directly with the lymphocytes or other cells of a potential allograft donor; presence of these antibodies usually, if not always, contraindicates the performance of the transplantation because virtually all such grafts will be subject to a hyperacute type of rejection. (05 Mar 2000) |
| cross-pollination | <botany> Fertilization of a plant from a plant with a different genetic makeup. (09 Oct 1997) |
