| 영문 | facial nerve | 한글 | 얼굴신경 |
|---|---|---|---|
| 설명 | 표정근을 지배하는 큰 운동신경과 작은 중간신경으로 구성된다. 좁은 의미의 얼굴신경과 중간신경으로 이루어지는 혼합신경이다. 속귀신경과 함께 속귓길로 들어가고 그 바닥에서 속귀신경과 갈라져 얼굴신경관으로 들어가, 거의 직각으로 구부러지는 부분을 얼굴신경무릎이라 하며, 여기에 무릎신경마디가 있다. |

|---|---|---|---|
| 설명 | 안쪽장딴지피부신경 및 온장딴지신경의 교통지에서 시작하여 가쪽배쪽피부신경 및 가쪽발꿈치가지의 가지를 낸다. 넙다리 등쪽의 피부, 발꿈치와 발의 가쪽의 피부 및 관절에 분포하며, 일반 감각성 기능을 한다. |

|---|---|---|---|
| 설명 | 척수의 앞뿔에서 출발하는 운동신경과 뒷뿔으로 들어오는 감각신경이 합쳐서 형성되는 신경으로서 총 31쌍이 존재함. 목뼈신경이 8쌍, 자등뼈신경이 12쌍, 허리뼈의 신경이 5쌍, 엉치뼈의 6쌍을 이룸. |

| 영문 | auditory nerve | 한글 | 청신경 |
|---|---|---|---|
| 설명 | 귀에서 감지된 청각의 신호를 대뇌로 보내는 역할을 하는 신경. 달팽이신경라고 불리기도 한다. 그것은 소리를 전기적 신호로 바꾸어 신경으로 전달해 주는 달팽이의 집같이 생긴 기관을 달팽이라고 부르기 때문이다. ![]() |

| poloidal field coil | <radiobiology> In toroidal devices (e.g., tokamaks), the sets of windings which are (typically) aligned along the plasma axis and produce poloidal fields. These include ohmic heating, shaping, vertical, equilibrium, and divertor windings. (09 Oct 1997) |

| curvature of field | <microscopy> A property of lens that causes the image of a plane to be focused into a curved surface instead of a plane. The image plane formed by a single lens is naturally curved. While one part of the field will be in good focus, the rest will need refocusing to be sharp. While the eye may partially correct for this, a camera lens will not, and the final image as photographed will not be in perfect focus over the entire image plane. (05 Aug 1998) |

| pulsed-field gel electrophoresis | Gel electrophoresis in which, after electrophoretic migration has begun, the current is briefly stopped and reapplied in a different orientation; allows for the purification of long DNA molecules. Synonym: pulsed-field gel electrophoresis. (05 Mar 2000) |
| pulse field electrophoresis | <investigation> A method used for high resolution electrophoretic separation of very large (megabase) fragments of DNA. Electric fields 100 |
| pulse-field gel electrophoresis | Gel electrophoresis in which, after electrophoretic migration has begun, the current is briefly stopped and reapplied in a different orientation; allows for the purification of long DNA molecules. Synonym: pulsed-field gel electrophoresis. (05 Mar 2000) |
| dark-field condenser | An apparatus for throwing reflected light through the microscope field, so that only the object to be examined is illuminated, the field itself being dark. (05 Mar 2000) |
| dark field illumination | <microscopy> Any method of illumination which illuminates the specimen but does not admit light directly to the objective. It may be by substage (dark field) condensers, by stagespot lighting, by special condensers fitted around special objectives for reflected illumination or by the slit ultramicroscope. (05 Aug 1998) |
| dark field imaging | <microscopy> Using a single diffracted beam to form the image in a transmission electron microscope. This causes all regions of the specimen not of the same crystal structure and orientation as the region which produced the diffracted beam to be represented as very dark in the final image, allowing phase differentiation visually in the transmission electron microscope. (05 Aug 1998) |
| dark-field microscope | <instrument> A microscope that has a special condenser and objective with a diaphragm or stop that scatters light from the object observed, with the result that the object appears bright on a dark background. (05 Mar 2000) |
| dark field microscopy | <procedure> A system of microscopy in which particles are illuminated at a very low angle from the side so that the background appears dark and the objects are seen by diffracted and reflected patches of light against a dark background. (18 Nov 1997) |
| dark field objective | <microscopy> Certain objectives for high-power, dark fieldwork equipped with iris diaphragms or funnel stops so that their apertures may be reduced to correspond to the dark field con-denser with which they are used. (05 Aug 1998) |
| dark field slides | <microscopy> Owing to the exacting demands of dark field illumination, not only must the microscope slide be especially clean, but also the glass of which the slide is composed must be optically clear under dark field conditions. The glass should not fluoresce. (05 Aug 1998) |
| dark field stop | <microscopy> A central stop for obtaining a dark field effect for low-power objectives. It is customarily used with a high numerical aperture, bright field condenser. (05 Aug 1998) |
| depth of field | <microscopy> The depth or thickness of the object space that is simultaneously in acceptable focus. The distance between the closest and farthest objects in focus within a scene as viewed by a lens at a particular focus and with given settings. The depth of field varies with the focal length of the lens and its f-stop setting or numerical aperture, and the wavelength of light. Depth of fields only a small fraction of a micrometre can be achieved at 546 nm with microscope lenses of N.A. Greater than 0.9. (05 Aug 1998) |
