| 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) |

| 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) |
| anterior margin | The ventral or most forward margin of a structure. Synonym: anterior margin, ventral border. (05 Mar 2000) |
| articular margin | A ring of fibrocartilage attached to the margin of the glenoid cavity of the scapula to increase its depth. Synonym: labrum glenoidale, articular margin, circumferential cartilage, glenoid ligament, glenoidal lip, ligamentum glenoidale. (05 Mar 2000) |
| margin | 1. A border; edge; brink; verge; as, the margin of a river or lake. 2. Specifically: The part of a page at the edge left uncovered in writing or printing. 3. The difference between the cost and the selling price of an article. 4. Something allowed, or reserved, for that which can not be foreseen or known with certainty. 5. Collateral security deposited with a broker to secure him from loss on contracts entered into by him on behalf of his principial, as in the speculative buying and selling of stocks, wheat, etc. Margin draft, that part of a course, as of slates or shingles, which is not covered by the course immediately above it. See Gauge. Synonym: Border, brink, verge, brim, rim. Origin: OE. Margine, margent, L. Margo, ginis. Cf. March a border, Marge. Source: Websters Dictionary (01 Mar 1998) |
| margin of acetabulum | The rim of bone around the acetabulum to which is attached the labrum acetabulare. Synonym: limbus acetabuli, margo acetabularis. (05 Mar 2000) |
| margin of fossa ovalis | A muscular ring surrounding the fossa ovalis in the wall of the right atrium of the heart. Synonym: annulus ovalis, margin of fossa ovalis, Vieussens' annulus, Vieussens' isthmus, Vieussens' limbus, Vieussens' ring. (05 Mar 2000) |
