| Kerley B lines | Fine peripheral septal lines. Synonym: costophrenic septal lines. (05 Mar 2000) |
|---|---|
| Kerley C lines | A non-specific fine reticular pattern on chest radiographs. (05 Mar 2000) |
| Zollner's lines | Figures devised to show the possibility of optical illusions; a common one consists of two parallel line's which are met by numerous short lines obliquely placed; the parallel lines then seeming to converge or diverge. (05 Mar 2000) |
| field lines | <radiobiology> Lines in space along which a field is either changing or not changing (depends on the kind of field) but which help to create diagrams which characterise the behaviour and effects of the field. For instance, electric field lines run in the direction that the electric field will push charged particles, the strength of the field is proportional to the density of the field lines. On the other hand, the magnetic force pushes particles in a direction perpendicular to both the particle's velocity and the direction of the magnetic field line. (09 Oct 1997) |
| fleischner lines | <radiology> Long line shadows (fibrotic scar) from invagination of pleura at the base of the collapse resulting in pseudofissure, seen in pulmonary infarction (12 Dec 1998) |
| Langer's lines | Lines which can be extrapolated by connecting linear openings made when a round pin is driven into the skin of a cadaver, resulting from the principal axis of orientation of the subcutaneous connective tissue (collagen) fibres of the dermis; they vary in direction with the region of the body surface. Synonym: Langer's lines. (05 Mar 2000) |
| fraunhofer lines | <physics> The lines of the spectrun; especially and properly, the dark lines of the solar spectrum, so called because first accurately observed and interpreted by Fraunhofer, a German physicist. Source: Websters Dictionary (01 Mar 1998) |
| Fraunhofer's lines | A number of the most prominent of the absorption line's of the solar spectrum. (05 Mar 2000) |
| LINES | <abbreviation> Long interspersed elements. (05 Mar 2000) |
| lines of Zahn | Riblike markings seen by the naked eye on the surface of antemortem thrombi; they consist of a branching framework of platelets and fibrin separating the coagulated blood cells. Synonym: striae of Zahn. (05 Mar 2000) |
| Looser's lines | Radiolucent bands in the cortex of a bone; usually indicates osteomalacia. Synonym: Looser's zones. (05 Mar 2000) |
| anterior condyloid foramen | The canal through which the hypoglossal nerve emerges from the skull. Synonym: canalis hypoglossalis, anterior condyloid canal of occipital bone, anterior condyloid foramen. (05 Mar 2000) |
| anterior palatine foramen | An opening in the posterolateral corner of the hard palate opposite the last molar tooth, marking the lower end of the pterygopalatine canal. Synonym: foramen palatinum majus, anterior palatine foramen. (05 Mar 2000) |
| aortic foramen | The opening in the diaphragm bounded by the two crura, the vertebral column, and the median arcuate ligament, through which pass the aorta and thoracic duct. Synonym: hiatus aorticus, aortic foramen, aortic opening. (05 Mar 2000) |
| apical dental foramen | The opening at the apex of the root of a tooth that gives passage to the nerve and blood vessels. Synonym: foramen apicis dentis, apical dental foramen, root foramen. (05 Mar 2000) |
