| 설명 | 망막의 구조를 직상검안경(망막을 보기 위해 고안된 검사기구)으로 보면 다음과 같다. 망막에 혈액을 공급하는 망막동맥(retinal artery)과, 다시 혈액을 회수하는 망막정맥(retinal vein)은 다같이 시각신경(optic nerve)과 함께 시각신경구멍(optic foramen)을 통해 망막까지 이르게 된다. 즉, 이들 망막 동, 정맥은 시각신경속에 끼워진 채 망막까지 이르게 된다. 따라서 이들 망막 동, 정맥 주위에 존재하는 시각신경유두는 바로 시각신경의 일부분을 말한다. 빛의 자극을 이해할 수 있는 신호체계로 바꾸는 시각세포는 받아들인 자극을 시각신경에서 분지한 수많은 신경절세포(ganglion cell: 신경전달을 모아서 보다 큰 전달단위로 전해주는 역할을 하며, 망막내에 위치한다)로 전달하게 되고, 이들 신경절세포는 다시 이런 자극들을 모아 시각신경유두로 보내게 되며, 시각신경유두에서부터 신경전달은 뇌까지 진행한다.  |

| 영문 | intervertebral disk | 한글 | 척추원반, 추간판 |
|---|---|---|---|
| 설명 | 척추동물에서 척주의 척추뼈 사이에 있는 원반처럼 생긴 척추뼈사이조직. 제2목뼈 이하 제5허리뼈와 엉치뼈바닥 사이에 있으며, 사람은 보통 23개이다. 개개의 원반은 중앙부가 가장 두껍다. 원반의 가쪽부는 결합조직과 섬유연골로 되어 있는 섬유테가 있고, 내부의 중앙은 연골세포군과 부드러운 섬유연골로 되어 있는 섬유테가 있고, 내부의 중앙은 연골세포군과 부드러운 섬유연골로 된 속질핵이 있으며, 여기에는 다량의 수분이 함유되어 있다. 척주의 부위에 따라서 원반의 두께가 다른데 등뼈가 가장 얇다. 이것은 그 구조상 강한 탄력성과 팽창성을 가지고 있으며, 척주의 굴신운동이나 척주를 중심으로 하는 몸의 지지에 중요한 역할을 하고 있다. 이러한 척추원반이 외상을 받아서 섬유륜의 퇴행변성을 일으켜 속질핵이 헤르니아를 일으킨 것을 척추원반탈출증이라고 한다. 척주의 운동은 이 척추원반의 탄력성과 척주 뒷부분의 척추관절에 의하여 가능하게 된다. |

| absolute filter | <apparatus> A fine-pored, steam-sterilisable filter that is used to trap airborne microorganisms. The filter's pores are about 2 micrometres in diameter, smaller than the particles it is designed to remove. (06 May 1997) |
|---|---|
| bandpass filter | A device that allows a limited range of frequencies to pass. (05 Mar 2000) |
| Berkefeld filter | A bacterial filter used in 1891, made of earth known as Kieselguhr taken from the name of the mine in Hanover, Germany, from which the earth was found. Ground water at this mine had a clear blue colour suggesting the use of the earth as a filter. Origin: Berkefield, name of owner of the mine from which the material to make the filter was taken (05 Mar 2000) |
| bird's nest filter | A wire mesh vena cava filter. (05 Mar 2000) |
| bird's nest ivc filter | <radiology> Introduced 1982; Cook Inc., Bloomington, IN advantages, low profile: 14.5 Fr introducer sheath, low recurrent PE rates (1.1 - 2.7% by clinical history), low IVC thrombosis rates (2.9 - 5.0% by clinical history), placement in large diameter IVCs (not greater than40mm), free-form configuration does not require centreing in IVC disadvantages: stainless steel: ferromagnetic = magnetic susceptibility artifact, more operator dependent, difficult to place in short IVCs (need about 7cm for proper placement), prolapse of filter wires (? clinical significance) see also: indications (12 Dec 1998) |
| vena cava filter | A filter used for interruption of IVC to prevent pulmonary embolism; e.g., Greenfield filter. Synonym: venocaval filter. (05 Mar 2000) |
| vena-tech ivc filter | <radiology> Introduced as LGM (L.G. Medical, France), 1985; FDA aprroval 1991: Vena-Tech, Evanston, IL, 6-leg conical design with 6 stabilizing side bars, biocompatible metal known as Phynox (cobalt,chromium,iron,nickel,moly) Efficacy, recurrent PE: 2-6%, IVC occlusion: 8-24%, migration: 0-12% Advantages, ease of placement, excellent clot trapping efficiency, low profile, lacks ferromagnetic activity: minimal MRI artifacts Disadvantages, incomplete opening (6-19%): decreases clot-trapping efficiency, increased incidence from IJ approach, decreased with rapid deployment, increased IVC thrombosis rates: 8% initial reports; 22-24% on subsequent reports by ultrasound/MRI: 2-19% clinically symptomatic (12 Dec 1998) |
| venocaval filter | A filter used for interruption of IVC to prevent pulmonary embolism; e.g., Greenfield filter. Synonym: venocaval filter. (05 Mar 2000) |
| Rheinberg filter | <equipment> A colour-filter disk to be placed, as a dark field stop would be placed, below the substage condenser. The central circular area, that is filled with one of the two or three colour filters, should safely subtend the objective aperture. The annular quadrants around this are normally contrasting in colour. This is/are the colour shown by the organisms or other specimen detail against the coloured field. The effect is one kind of optical staining. (05 Aug 1998) |
| Greenfield filter | A multistrutted spring-styled filter usually placed in the inferior vena cava to prevent venous emboli from reaching the pulmonary circulation from the lower extremity. (05 Mar 2000) |
| micropore filter | A filter made of a meshwork of cellulose acetate or nitrate and with defined pore size. They can be autoclaved and the smaller pore sizes (0.22m,0.45m) are used for sterilising heat labile materials by filtering out micro organisms. Larger pore size filters are used in setting up Boyden chambers. They are about 150m thick and should be distinguished from Nucleopore filters. Millipore is a trade name for micropore filters. (18 Nov 1997) |
| Millipore filter | <cell culture, equipment> Trade name for a well known brand of micropore filters. (12 Jan 1998) |
| hemming filter | <apparatus> A filter placed between two tubes attached to each other, often used with centrifuges to selectively remove a substance of interest from a mixture in one tube and deposit the substance into the other tube. (09 Oct 1997) |
| high-pass filter | A device or material that allows high frequency signals to pass while attenuating other signals. (05 Mar 2000) |
| high quality filter paper | Used in paper chromatography. Synonym: high quality filter paper. Congo red paper, paper impregnated with Congo red; used as a pH indicator, changing from blue-violet at 3.0 to red at 5.0. Filter paper, an unsized paper used in pharmacy and chemistry for filtering solutions; many varieties are used for paper chromatography. (05 Mar 2000) |
