| fissure of round ligament of liver | A cleft on the inferior surface of the liver, running from the inferior border to the left extremity of the porta hepatis; it lodges the round ligament of the liver. Synonym: fissura ligamenti teretis, fissure for ligamentum teres, fossa venae umbilicalis, umbilical fissure, umbilical fossa. (05 Mar 2000) |
|---|---|
| fissure of venous ligament | A deep cleft extending from the porta hepatis and the inferior vena cava between the left lobe and the caudate lobe; it lodges the ligamentum venosum and is thus a vestige of the fossa of the ductus venosus. Synonym: fissura ligamenti venosi, fissure of venous ligament. (05 Mar 2000) |
| fissure sealant | A dental material usually made from interaction between bisphenol A and glycidyl methacrylate; such sealant's are used to seal nonfused, noncarious pits and fissures on surfaces of teeth. Synonym: dental sealant. (05 Mar 2000) |
| fissure sign | In perfusion scintigraphy of the lungs, decreased uptake of radionuclide in the periphery of each lobe, making the fissures visible; caused by a variety of diseases and artifacts. (05 Mar 2000) |
| lateral cerebral fissure | The deepest and most prominent of the cortical fissures, extending from the anterior perforated substance first laterally at the deep incisure between the frontal and temporal lobes, then back and slightly upward over the lateral aspect of the cerebral hemisphere, with the superior temporal gyrus as its lower bank, the insula forming its greatly expanded floor. Two short side branches, the ramus anterior and ramus ascendens, divide the inferior frontal gyrus into an orbital part, triangular part, and opercular part. Synonym: sulcus lateralis cerebri, fissura cerebri lateralis, lateral cerebral fissure, sylvian fissure, fissure of Sylvius. (05 Mar 2000) |
| left sagittal fissure | A sagittal groove on the undersurface of the liver formed by the fissura ligamenti teretis anteriorly and the fissura ligamenti venosi posteriorly. (05 Mar 2000) |
| linguogingival fissure | A fissure sometimes occurring on the lingual surface of one of the upper incisors and extending into the cementum. (05 Mar 2000) |
| longitudinal fissure of cerebrum | The deep cleft separating the two hemispheres of the cerebrum. Synonym: fissura longitudinalis cerebri, great longitudinal fissure. (05 Mar 2000) |
| lunate fissure | A small, inconstant semilunar groove on the cortical convexity near the occipital pole, marking the anterior border of the striate cortex (area 17) and considered homologous with the major sulcus of the same name that is a more constant feature of the cerebral cortex in monkeys and apes. Synonym: sulcus lunatus cerebri, ape fissure, lunate fissure, lunate sulcus, simian fissure. (05 Mar 2000) |
| air-conditioner lung | An extrinsic allergic alveolitis caused by forced air contaminated by thermophilic actinomycetes and other organisms. (05 Mar 2000) |
| airless lung | <radiology> Tumour, foreign body, mucous plug (12 Dec 1998) |
| anterior border of lung | The thin anteromedial or sternal edge of the lung which overlaps the pericardial sac anteriorly and forms the boundary between the mediastinal and costal surfaces. Synonym: margo anterior pulmonis. (05 Mar 2000) |
| apex of lung | The rounded, upper extremity of each lung that extends into the cupula of the pleura. Synonym: apex pulmonis. (05 Mar 2000) |
| apical interstitial lung disease | <radiology> A radiological diagnosis where fibrosis is seen in the apices (upper sections) of the lungs. Likely causes include: cystic fibrosis, ankylosing spondylitis, sarcoidosis, silicosis, eosinophlic granuloma, TB and fungus, particularly aspergillus infection. (25 Jun 1999) |
| asbestos lung disease | <radiology> Pleural plaques, earliest finding, may be only evidence, parietal pleura, 15-20 yrs after exposure, calcified after ca. 30 yrs, asbestosis, interstitial lung disease, perihilar regions to lung bases, shaggy heart, no cavitation or progressive massive fibrosis as in silicosis, crocidolite (blue) form most carcinogenic, associated with: malignant pleural mesothelioma, peritoneal mesothelioma, GI-tract malignancy (12 Dec 1998) |
