| 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) |
| costophrenic septal lines | Fine peripheral septal lines. Synonym: costophrenic septal lines. (05 Mar 2000) |
| Harris' 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) |
| Head's lines | Bands of cutaneous hyperesthesia associated with acute or chronic inflammation of the viscera. Synonym: Head's zones, tender lines, tender zones. (05 Mar 2000) |
| Salter's incremental lines | Transverse line's sometimes seen in dentin, due to improper calcification. (05 Mar 2000) |
| Schreger's lines | Alternating light and dark lines seen in dental enamel that begin at the dentoenamel junction and end before they reach the enamel surface; they represent areas of enamel rods cut in cross-sections dispersed between areas of rods cut longitudinally. Synonym: Hunter-Schreger lines, Schreger's lines. (05 Mar 2000) |
| septal lines | Radiographic images of thickened interlobular septa, most often along the lateral border of lung, extending to pleura; Kerley A and B lines; usually caused by septal oedema and fibrosis, also carcinomatosis. (05 Mar 2000) |
| Hunter-Schreger lines | Alternating light and dark lines seen in dental enamel that begin at the dentoenamel junction and end before they reach the enamel surface; they represent areas of enamel rods cut in cross-sections dispersed between areas of rods cut longitudinally. Synonym: Hunter-Schreger lines, Schreger's lines. (05 Mar 2000) |
