| auscultatory sound | A rale, murmur, bruit, fremitus, or other sound heard on auscultation of the chest or abdomen. (05 Mar 2000) |
| Barcroft-Warburg apparatus | An apparatus for measuring the oxygen consumption of incubated tissue slices by manometric measurement of changes in gas pressure produced by oxygen absorption in an enclosed flask. Synonym: Barcroft-Warburg apparatus. (05 Mar 2000) |
| Beckmann's apparatus | Apparatus for the accurate measurement of melting points and boiling points in connection with molecular weight determinations. (05 Mar 2000) |
| bell sound | In cases of a large pulmonary cavity or of pneumothorax, a clear metallic sound obtained by striking a coin, held against the chest, by another coin, or by flicking the chest wall with one's fingernail; the sound is heard on auscultating the chest wall on the same side anteroposteriorly. Synonym: anvil sound, bell sound, coin test. (05 Mar 2000) |
| Benedict-Roth apparatus | <apparatus, physiology> A device employed to measure the amount of oxygen utilised in quiet breathing in the basal state for the estimation of the basal metabolic rate; the subject rebreathes oxygen through soda lime from a recording spirometer. (14 Aug 2000) |
| branchial apparatus | The aggregate of the pharyngeal arches, pouches, clefts, and membranes seen in the developing embryo of vertebrates. (05 Mar 2000) |
| Campbell sound | A miniature sound with a short round-tipped beak, especially curved for the deep urethra of the young male. (05 Mar 2000) |
| cannon sound | The loud first heart sound heard intermittently in complete atrioventricular block and in interference-dissociation when the ventricles happen to contract shortly after the atria. Synonym: cannon sound. (05 Mar 2000) |
| cardiac sound | The sounds heard over the cardiac region produced by the functioning of the heart. There are four distinct sounds: the first occurs at the beginning of systole and is heard as a "lubb" sound; the second is produced by the closing of the aortic and pulmonary valves and is heard as a "dupp" sound; the third is produced by vibrations of the ventricular walls when suddenly distended by the rush of blood from the atria; and the fourth is produced by atrial contraction and ventricular filling but is rarely audible in the normal heart. The physiological concept of heart sounds is differentiated from the pathological heart murmurs. (12 Dec 1998) |
| gallop sound | The abnormal third or fourth heart sound which, when added to the first and second sound's, produces the triple cadence of gallop rhythm. See: gallop. (05 Mar 2000) |
| van Buren sound | A standard sound, available in several calibers, with a gently curved tip designed to follow the contour of the deep bulbous urethra in the male; used for urethral calibration or dilation. (05 Mar 2000) |
| Van Slyke apparatus | An apparatus for determining the amounts of respiratory gases in the blood. (05 Mar 2000) |
| genitourinary apparatus | The organs concerned in the production and excretion of urine, together with the organs of reproduction. (12 Dec 1998) |
| masticatory apparatus | The organs and structures primarily functioning in mastication: the jaws, teeth with their supporting structures, temporomandibular joint, muscles of mastication, tongue, lips, cheeks, and oral mucosa. Synonym: dental apparatus, masticatory apparatus. (05 Mar 2000) |
