| A-a | alveolar-atrial |
| ureteric bud | The primordial cellular outgrowth from the mesonephric duct that gives rise to the epithelial lining of the ureter, of the pelvis, and calyces of the kidney, and of the straight collecting tubules. Synonym: ureteric bud. (05 Mar 2000) |
|---|---|
| limb bud | The limbs of vertebrates start as outpushings of mesenchyme surrounded by a simple epithelium. The distal region is referred to as the progress zone. There has been extensive study of positional information within the limb bud that determines, for example: the proximal distal pattern of bone development and the anterior posterior specification of digits. (18 Nov 1997) |
| liver bud | The primordial cellular diverticulum of the embryonic foregut endoderm that gives rise to the parenchyma of the liver. (05 Mar 2000) |
| lung bud | The endodermal lung primordium which will give rise to the epithelial lining of the respiratory tract. Synonym: lung bud. (05 Mar 2000) |
| adenocarcinoma, bronchiolo-alveolar | A carcinoma thought to be derived from epithelium of terminal bronchioles, in which the neoplastic tissue extends along the alveolar walls and grows in small masses within the alveoli. Involvement may be uniformly diffuse and massive, or nodular, or lobular. The neoplastic cells are cuboidal or columnar and form papillary structures. Mucin may be demonstrated in some of the cells and in the material in the alveoli, which also includes denuded cells. Metastases in regional lymph nodes, and in even more distant sites, are known to occur, but are infrequent. (12 Dec 1998) |
| alveolar | <anatomy> Of, pertaining to, or resembling, alveoli or little cells, sacs, or sockets. Alveolar processes, the processes of the maxillary bones, containing the sockets of the teeth. Origin: L. Alveolus a small hollow or cavity: cf. F. Alveolaire. Source: Websters Dictionary (01 Mar 1998) |
| alveolar abscess | A pocket of pus adjacent to or within (apical abscess) the tooth's root caused by plaque and calculus invasion. Symptoms include tooth pain and tenderness that may be accompanied by facial swelling and a fever. Treatment includes antibiotics and a thorough cleansing of the infected site by a dentist. See: apical abscess. (27 Sep 1997) |
| alveolar adenocarcinoma | <tumour> Adenocarcinoma of the lung in which tumour cells form structures resembling alveoli. (05 Mar 2000) |
| alveolar air | The gas in the pulmonary alveoli, where O2-CO2 exchange with pulmonary capillary blood occurs. Synonym: alveolar air. (05 Mar 2000) |
| alveolar angle | The angle between the horizontal plane and a line connecting the base of the nasal spine and the middle point of the projection of the alveolus of the maxilla. (05 Mar 2000) |
| alveolar arch of mandible | The free margin of the alveolar process of the mandible. Synonym: arcus alveolaris mandibulae, limbus alveolaris. (05 Mar 2000) |
| alveolar arch of maxilla | The free border of the alveolar process of the maxilla. Synonym: arcus alveolaris maxillae, limbus alveolaris. (05 Mar 2000) |
| alveolar-arterial oxygen difference | The difference or gradient between the partial pressure of oxygen in the alveolar spaces and the arterial blood: P(A-a)02. Normally in young adults this value is less than 20 mm Hg. See: alveolar gas equation. (05 Mar 2000) |
| alveolar atrophy | Diminution in size of the supportive tissues of the teeth due to lack of function, reduced blood supply, or unknown causes. (05 Mar 2000) |
| alveolar body | That portion of bone in either the maxilla or the mandible which surrounds and supports the teeth. (12 Dec 1998) |
