| 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) |
|---|---|
| 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) |
| developmental lines | Fine lines found in the enamel of a tooth that mark the junction of the lobes of the crown in its development. Synonym: developmental lines. (05 Mar 2000) |
| imbrication lines of von Ebner | Incremental line's in the dentin of the tooth that reflect variations in mineralization during dentin formation; the distance between the line's corresponds to the daily rate of dentin formation. Synonym: incremental lines of von Ebner. (05 Mar 2000) |
| incremental lines | In the enamel, calcification line's of Retzius, in the dentin, imbrication or incremental line's of von Ebner, and Owen's line's. (05 Mar 2000) |
| incremental lines of von Ebner | Incremental line's in the dentin of the tooth that reflect variations in mineralization during dentin formation; the distance between the line's corresponds to the daily rate of dentin formation. Synonym: incremental lines of von Ebner. (05 Mar 2000) |
| Owen's lines | 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) |
| tender 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) |
| Eberth's lines | Line's appearing between the cells of the myocardium when stained with silver nitrate. (05 Mar 2000) |
| tram lines | The images of bronchial walls, usually thickened; colloq., British. Synonym: radiographic parallel line shadows. (05 Mar 2000) |
| transverse lines of sacrum | One of four ridges that cross the pelvic surface of the sacrum; these mark the positions of the intervertebral disks between the bodies of the five sacral vertebrae in the immature bone. Synonym: lineae transversa ossi sacri. (05 Mar 2000) |
| Kerley A lines | Images of deep interlobular septa; longer, thicker, and more central than Kerley B lines; usually in upper lobes. (05 Mar 2000) |
