| alveolar hydatid cyst | A hydatid cyst of a multiloculate type, usually in the liver, caused by Echinococcus multilocularis, adults of which are in foxes; larvae (alveolar hydatid) are found chiefly in microtine rodents, but also among humans such as trappers and others handling pelts of infected foxes and other carnivores; growth is by exogenous budding and is not limited by an outer laminated membrane as in the hydatid cyst from E. Granulosus; necrosis, cavitation, contiguous spread, and death usually ensue. Synonym: multilocular hydatid cyst, multiloculate hydatid cyst. (05 Mar 2000) |

| alveolar index | Relation between the basialveolar (basion to alveolar point) and basinasal (basion to nasion) lengths: (basialveolar length × 100)/basinasal length; the result indicates the degree of projection of the maxilla or upper jaw. Synonym: alveolar index. (05 Mar 2000) |
| alveolar macrophage | Macrophage found in lung and that can be obtained by lung lavage, responsible for clearance of inhaled particles and lung surfactant. Metabolism slightly different from peritoneal macrophages (more oxidative metabolism), often have multivesicular bodies that may represent residual undigested lung surfactant. (18 Nov 1997) |
| alveolar macrophage elastase | <enzyme> Metalloproteinase found in human alveolar macrophages Registry number: EC 3.4.24.- Synonym: elastase, alveolar macrophage, metalloproteinase elastase, human macrophage metalloelastase, mmp12 gene product, mmp-12 gene product, mme gene product, macrophage metalloelastase (26 Jun 1999) |
| alveolar mucosa | The mucous membrane apical to the attached gingiva. (05 Mar 2000) |
| alveolar osteitis | A postoperative complication of tooth extraction in which the blood clot in the socket disintegrates, resulting in focal osteomyelitis and severe pain. Synonym: alveolalgia, alveolar osteitis, dry socket. Origin: alveolus + G. Algos, pain (05 Mar 2000) |
| alveolar part of mandible | The portion of the body of the mandible that surrounds and supports the lower teeth. Synonym: pars alveolaris mandibulae. (05 Mar 2000) |
| alveolar pattern | Cloudy to dense opacities, obscuring vascular markings, on chest radiographs. Synonym: airspace-filling pattern. (05 Mar 2000) |
| alveolar periosteum | <anatomy> Fibrous connective tissue surrounding the root of a tooth that separates it from and attaches it to the alveolar bone. (12 Dec 1998) |
| alveolar point | The most anterior point on the maxillary alveolar process in the midline. Synonym: alveolar point, prostheon. Origin: G. Ntr. Of prosthios, foremost (05 Mar 2000) |
| alveolar process | That portion of bone in either the maxilla or the mandible which surrounds and supports the teeth. (12 Dec 1998) |
| alveolar proteinosis | A very rare disease in which a phospholipid is widely distributed in cells and accumulates in the alveolar spaces in the lung. In some cases the underlying cause is unknown. In others it may relate to an infection or an immune system dysfunction. The net effect is a progressive interference in the ability of the lung (alveoli) to exchange oxygen and carbon dioxide. Symptoms include cough, weight loss, fatigue, shortness of breath and nail abnormalities (clubbing). Chest X-ray may show infiltrates, but a bronchoscopy with trans-tracheal biopsy is necessary to make a tissue diagnosis or alveolar proteinosis. Spontaneous remission may occur in some individuals while complete respiratory failure occurs in others. (27 Sep 1997) |
| alveolar ridge | That portion of bone in either the maxilla or the mandible which surrounds and supports the teeth. (12 Dec 1998) |
| alveolar ridge augmentation | Preprosthetic surgery involving rib, cartilage, or iliac crest bone grafts, usually autologous, or synthetic implants for rebuilding the alveolar ridge. (12 Dec 1998) |
| alveolar sac | Terminal dilation of the alveolar ducts that give rise to alveoli in the lung; a small air chamber in the pulmonary tissue from which the pulmonary alveoli project like bays and into which an alveolar duct opens; in birds, air-containing extensions of bronchi that connect with bone cavities. Synonym: sacculus alveolaris, air sac. (05 Mar 2000) |
