| 설명 | 1. 머리뼈내의 단단한 뼈로 구성된 공동을 말하며, 눈알-눈확지방-눈밖근-시간신경과 여러 가지 혈관-신경-섬유조직 등이 들어있다. 이와 같은 구조는 눈알이 회전하는 위치에서 잘 고정되어 있도록 해준다. 2. 궤도. 중력장 또는 전자기장 등에서 물체가 운동하는 일정한 길. 경로라고도 한다. 기준좌표계에 따라서 다르게 서술되기도 하며 좁은 의미로는 주기 운동을 하는 물체가 그리는 운동궤적인 폐곡선을 궤도라 하기도 한다. |

| 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) |
|---|---|
| apex of orbit | The posterior part of the orbit into which the optic canal opens; forms the tip of the pyramidal-shaped space. (05 Mar 2000) |
| banana orbit | <radiobiology> In a toroidal magnetic geometry, the fast spiraling of a charged particle around a magnetic field line is accompanied by a slow movement (drift) of the centre of the sprial. Particles with relatively low parallel energy are mirrored on the inside of the torus because the toroidal magnetic field has a 1/R dependence and is highest on the inside. The combination of mirroring and drift produces a special class of particle orbits. Projected onto a poloidal plane, the drift orbit has the shape of a banana. These orbits are responsible for neo-classical diffusion and bootstrap current. (09 Oct 1997) |
| margin of orbit | The mostly sharp edge of the orbital opening which is the peripheral border of the base of the pyramid-shaped orbit. The superior half of the orbital rim is the supraorbital margin; the inferior half is the infraorbital margin. The frontal, maxillary, and zygomatic bones contribute to the orbital rim, which is generally strong to protect the orbital contents. Weak, potential fracture sites of the rim coincide with the sutures between the participating bones. Synonym: margin of orbit. (05 Mar 2000) |
| medial wall of orbit | The thin, rectangular wall of the orbit formed by the orbital plate of the ethmoid, lacrimal, frontal and a small part of the sphenoid bones; the fossa for the lacrimal sac lies at its anterior limit. Synonym: paries medialis orbitae. (05 Mar 2000) |
| roof of orbit | Formed by the orbital plate of the frontal bone and the lesser wing of the sphenoid bone, the optic canal opens at its posterior limit; an indentation, the fossa for the lacrimal gland, is located in the anterolateral part of the roof. Synonym: paries superior orbitae, superior wall of orbit. (05 Mar 2000) |
| superior wall of orbit | Formed by the orbital plate of the frontal bone and the lesser wing of the sphenoid bone, the optic canal opens at its posterior limit; an indentation, the fossa for the lacrimal gland, is located in the anterolateral part of the roof. Synonym: paries superior orbitae, superior wall of orbit. (05 Mar 2000) |
| inferior wall of orbit | The floor of the orbit; the shortest of the four walls of the orbit, sloping upward from the orbital margin; it is comprised of the maxilla and orbital process of the palatine bone. Synonym: paries inferior orbitae, inferior wall of orbit. (05 Mar 2000) |
| orbit | 1. <astronomy> The path described by a heavenly body in its periodical revolution around another body; as, the orbit of Jupiter, of the earth, of the moon. 2. An orb or ball. "Roll the lucid orbit of an eye." (Young) 3. <anatomy> The cavity or socket of the skull in which the eye and its appendages are situated. 4. <zoology> The skin which surrounds the eye of a bird. Origin: L. Orbita a track or rut made by a wheel, course, circuit, fr. Orbis a circle: cf. F. Orbite. See Orb. Source: Websters Dictionary (01 Mar 1998) |
| orbit evisceration | The surgical removal of the contents of the orbit. This includes the eyeball, blood vessels, muscles, fat, nerve supply, and periosteum. It should be differentiated from eye evisceration which removes the inner contents of the eye, leaving the sclera intact. (12 Dec 1998) |
| fat body of orbit | The mass of fat contained in the orbit that contributes to the support of the eyeball. Synonym: corpus adiposum orbitae, fat body of orbit. (05 Mar 2000) |
| floor of orbit | The floor of the orbit; the shortest of the four walls of the orbit, sloping upward from the orbital margin; it is comprised of the maxilla and orbital process of the palatine bone. Synonym: paries inferior orbitae, inferior wall of orbit. (05 Mar 2000) |
| lateral wall of orbit | A triangular wall of the orbit formed by the zygomatic bone, the greater wing of the sphenoid bone, and a small part of the frontal bone; posteriorly it is bounded by the superior and inferior orbital fissures. Synonym: paries lateralis orbitae. (05 Mar 2000) |
| 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) |
| Auger electron | An electron ejected from a lower energy orbital after a photoelectric interaction of an X-ray photon with a K-shell electron by the characteristic radiation photon; the Auger electron recoils with energy equal to the characteristic radiation less the difference in shell binding energies. See: photoelectric effect. (05 Mar 2000) |
