| 설명 | 질병의 진단이나 치료 또는 마취를 하기 위해 피부에서 거미막밑공간으로 바늘을 찌를 때가 있다. 이것은 셋째 허리뼈 아래쪽에서 시행한다. 척수가 첫째 허리뼈 아랫모서리에서 끝나고, 거미막밑공간은 둘째 엉치뼈 분절까지 뻗어 있기 때문에 이 부위는 바늘로 척수를 찌를 위험이 없다. 또 척추뼈고리판이 짧아 서로 겹쳐있지 않기 때문에 허리뼈 사이로 바늘을 찌를 수 있다. 이 부위의 거미막밑공간에는 척수신경 뿌리가 있으나, 이들은 뇌척수액속에 있기 때문에 바늘을 넣을 때 한쪽으로 밀려 손상받는 경우는 거의 없다. 배를 넓적다리에 붙일정도로 허리를 구부리면 고리판 사이가 더 벌어져 틈이 커진다. 바늘이 뚫고 지나가는 구조는 바깥에서 속으로 ① 피부, ② 피부밑조직, ③ 근육막, ④ 가시끝인대, ⑤ 가시사이인대, ⑥ 황색인대, ⑦ 경질막, ⑧ 거미막, ⑨ 뇌척수액이 된다.  |

| 영문 | spinal cord | 한글 | 척수 |
|---|---|---|---|
| 설명 | 척추내에 위치하는 중추신경계의 일부분. 위에서부터 목척수, 등척수, 허리척수, 엉치척수로 구분됨. 내부는 바깥쪽의 백색질과 안쪽의 회색질로 구분된다. 척수의 아래끝은 척수 원뿔이라 하며 첫번째 허리뼈 높이까지 내려온다. 뇌와 말초신경사이의 신경 통로 역할을 하며 척수반사(예: 무릎반사)에서는 뇌를 통하지 않고 반사의 중추 작용을 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. |

| angle of aperture | <ophthalmology, optics> The angle formed by lines drawn from the ends of the diameter of a lens to its point of focus. See: angular aperture. (05 Mar 2000) |
|---|---|
| angular aperture | The angle, in air, of light that passes from the object to the ends of the diameter of the front lens of the microscope objective. (05 Mar 2000) |
| anterior nasal aperture | The anterior nasal opening in the skull. Synonym: apertura piriformis, piriform opening. (05 Mar 2000) |
| aperture | <physics> The opening in an optical system which restricts the size of the bundle of rays incident on a given surface. (Usually circular and specified by diameter.) (09 Oct 1997) |
| aperture, angular | <microscopy> The angle between the most divergent rays that can pass through a lens to form the image of an object. The angle subtended between the axis of a lens and the largest accepted angle of the image-forming rays. With microscope objectives the trigonometric sine of this angle is used to define numerical aperture but as measured from the axial object point. (05 Aug 1998) |
| aperture correction | <microscopy> An electronic process used in some high-resolution video cameras and monitors that compensates for the loss in sharpness of detail due to the finite dimensions (aperture) of the scanning beam. (05 Aug 1998) |
| aperture diaphragm | A metal device that limits the area of the beam emerging from an X-ray tube. (05 Mar 2000) |
| aperture, effective | <microscopy> The diameter of the entrance pupil: it is the apparent diameter of the limiting aperture measured from the front. (05 Aug 1998) |
| aperture for electron microscopy | <technique> Anode aperture: The opening in the accelerating voltage anode shield of the electron gun through which the electrons must pass to irradiate the specimen. Condenser aperture: An opening in the condenser lens controlling the number of electrons entering the lens and the angular aperture of the electron beam. The angular aperture can also be controlled by the condenser lens current. Physical objective aperture: A metallic diaphragm, with a small central hole, used to limit the cone of electrons accepted by the objective lens. This improves image-contrast since highly scattered electrons are prevented from arriving at the Gaussian image plane and therefore cannot contribute to background fog. Aplanatic. Free from spherical aberration and coma. (05 Aug 1998) |
| aperture function | <microscopy> In a diffraction-limited optical system, the function that determines the relationship between the image and each point in the object. Modifying the aperture function changes the image according to the modified Fourier-filtering (or optical filtration) property of the aperture. (05 Aug 1998) |
| aperture of mastoid antrum | The orifice leading from the epitympanic recess to the mastoid antrum. Synonym: aditus ad antrum. (05 Mar 2000) |
| aperture of orbit | The somewhat quadrangular anterior entrance to the orbit which forms the base of the pyramid-shaped orbital cavity. It is bounded by the sharp supra-, infra-, and lateral orbital margins and a less obvious medial margin on each side of the upper nose. Synonym: aditus orbitae, aperture of orbit. (05 Mar 2000) |
| aperture plane | <microscopy> In a microscope adjusted for Koehler illumination, the conjugate planes that include the light source, the condenser iris diaphragm, the objective lens back aperture, and the eye point. Spaces in the aperture planes are the reciprocal of those in the field planes. (05 Aug 1998) |
| back aperture | <microscopy> The exit pupil of a microscope objective lens. The objective lens back aperture, which can be examined with a phase telescope or by inserting a Bertrand lens, displays the conoscopic interference figure and diffraction patterns. (05 Aug 1998) |
| relative aperture | <microscopy> The ratio of the focal length of a lens to the diameter of its entrance pupil. This gives a number known as the f-number, usually written f:8, f:16, etc. Thus, if the focal length is divided by the number 8, 16, etc., the result will be the diameter of the entrance pupil of the lens, or if the diaphragm of the lens is wide open it will be very nearly the diameter of the free aperture of the lens. See: F-number. (05 Aug 1998) |
