| sinuatrial chamber | <anatomy> The common chamber formed by the single embryonic atrium and the right and left horns of the sinus venosus. (20 Jun 2000) |
|---|---|
| specimen chamber | <microscopy> The compartment located in the column of the electron microscope in which the specimen is placed for observation. (05 Aug 1998) |
| decompression chamber | <apparatus> A steel chamber that is used to apply oxygen under pressure to reverse the effects of the bends or to treat other forms of barotrauma. Synonym: hyperbaric chamber. (27 Sep 1997) |
| ionization chamber | A chamber for detecting ionization of the enclosed gas; used for determining intensity of ionizing radiation. (05 Mar 2000) |
| orientation chamber | <cell culture> Chamber designed by Zigmond in which to test the ability of cells (neutrophils) to orient in a gradient of chemoattractant. The chamber is similar to a haemocytometer, but with a depth of only ca. 20m. The gradient is set up by diffusion from one well to the other and the orientation of cells towards the well containing chemoattractant is scored on the basis of their morphology or by filming their movement. (18 Nov 1997) |
| endothelium of anterior chamber | A single layer of large, squamous cells that covers the posterior surface of the cornea. Synonym: endothelium camerae anterioris. (05 Mar 2000) |
| Zappert counting chamber | A special, standardised glass slide used for counting cells (especially erythrocytes and leukocytes) and other particulate material in a measured volume of fluid; the central portion is precisely ground in such a manner that the uniformly flat surface is exactly 0.1 mm lower than that of two parallel ridges on which a special, uniformly flat coverslip may be placed; accurately etched lines on the flat central portion form the boundaries of groups of squares of known areas, thereby providing the basis for determining the volume of fluid in which the cells are counted. Glass slides of this type are frequently known as haemocytometers. (05 Mar 2000) |
| Zigmond chamber | <cell culture> Chamber designed by Zigmond in which to test the ability of cells (neutrophils) to orient in a gradient of chemoattractant. The chamber is similar to a haemocytometer, but with a depth of only ca. 20m. The gradient is set up by diffusion from one well to the other and the orientation of cells towards the well containing chemoattractant is scored on the basis of their morphology or by filming their movement. (18 Nov 1997) |
| alveolar dead space | The difference between physiologic dead space and anatomical dead space; it represents that part of the physiologic dead space resulting from ventilation of relatively underperfused or nonperfused alveoli; it differs specifically in being placed so as to fill and empty in parallel with functional alveoli, rather than being interposed in the conducting tubes between functional alveoli and the external environment. (05 Mar 2000) |
| anatomical dead space | The volume of the conducting airways from the external environment (at the nose and mouth) down to the level at which inspired gas exchanges oxygen and carbon dioxide with pulmonary capillary blood; formerly presumed to extend down to the beginning of alveolar epithelium in the respiratory bronchioles, but more recent evidence indicates that effective gas exchange extends some distance up the thicker-walled conducting airways because of rapid longitudinal mixing. Compare: alveolar dead space, physiologic dead space. Synonym: anatomical airway. (05 Mar 2000) |
| antecubital space | The fossa in front of the elbow, bounded laterally and medially by the humeral origins of the extensors and flexors of the forearm, respectively, and superiorly by an imaginary line connecting the humeral condyles. Synonym: fossa cubitalis, antecubital space, chelidon, triangle of elbow. (05 Mar 2000) |
| anterior clear space | On lateral chest radiographs, the region dorsal to the sternum and ventral to the ascending aorta. Synonym: anterior clear space. (05 Mar 2000) |
| apical space | The space between the alveolar wall and the apex of the root of a tooth where an alveolar abscess usually has its origin. (05 Mar 2000) |
| axillary space | <anatomy> The underarm area. (16 Dec 1997) |
| Berger's space | The space between the patellar fossa of the vitreous and the lens. (05 Mar 2000) |
