|---|---|
| absorption lines | The dark line's in the solar spectrum due to absorption by the solar and the earth's atmosphere; the phenomenon occurs because rays passing from an incandescent body through a colder medium are absorbed by elements in that medium. (05 Mar 2000) |
| accretion lines | Line's seen in microscopic sections of the enamel, marking successive layers of added material. (05 Mar 2000) |
| amphotropic packaging cell lines | <cell culture, molecular biology> Clonal entities that express genes or act as viral vectors that infect cell lines to stably infect and then express genes of choice. Usually an amphotropic virus. (04 Nov 1997) |
| Baillarger's lines | Two laminae of white fibres that course parallel to the surface of the cerebral cortex and are visible as outer and inner line's in sections cut perpendicular to the surface; the line of Gennari in the calcarine cortex represents the outer of these lines. Synonym: Baillarger's bands. (05 Mar 2000) |
| Beau's lines | Transverse depressions on the fingernails following severe febrile disease, malnutrition, trauma, myocardial infarction, etc. (05 Mar 2000) |
| calcification lines of Retzius | Incremental line's of rhythmic deposition of successive layers of enamel matrix during development. Synonym: lines of Retzius. (05 Mar 2000) |
| Paton's lines | Concentric lines on the surface of an abnormal retina. Synonym: Paton's lines. (05 Mar 2000) |
| Voigt's lines | A dorso-ventral line of pigmentation occurring symmetrically and bilaterally for about 10 cm along the lateral edge of the biceps muscle, seen in some blacks. Synonym: Voigt's lines. (05 Mar 2000) |
| Mees' lines | Horizontal white bands of the nails seen in chronic arsenical poisoning, and occasionally in leprosy. Synonym: Mees' stripes. (05 Mar 2000) |
| growth arrest lines | Dense lines parallel to the growth plates of long bones on radiographs, representing temporary slowing or cessation of longitudinal growth. Synonym: Harris' lines. (05 Mar 2000) |
| cleavage 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) |
| Muehrcke's lines | White line's, parallel with the lanula and separated from each other by normal pink areas; associated with hypoalbuminaemia; the line's do not move outward with nail growth, but disappear when the serum albumen returns to normal. (05 Mar 2000) |
| pleural lines | On a chest radiograph, the shadow of the soft tissues between the aerated lung and the bones of the thorax. Synonym: Correra's line. (05 Mar 2000) |
| contour lines of Owen | Accentuated incremental line's in the dentin thought to be due to disturbances in the mineralization process. Synonym: contour lines of Owen. (05 Mar 2000) |
