| kyphoscoliotic pelvis | A pelvis with marked anteroposterior curvature of the spine combined with lateral spinal curvature, usually due to severe rickets. (05 Mar 2000) |
|---|---|
| kyphotic pelvis | Backward curvature of the lumbar spine causing contraction of pelvic measurements. (05 Mar 2000) |
| flat pelvis | A pelvis in which the anteroposterior diameter is uniformly contracted, the sacrum being dislocated forward between the iliac bones. Synonym: pelvis plana. (05 Mar 2000) |
| large pelvis | The expanded portion of the pelvis above the brim. Synonym: pelvis major, false pelvis, large pelvis, pelvis spuria. (05 Mar 2000) |
| frozen pelvis | A condition in which the true pelvis is indurated throughout, especially by carcinoma. Synonym: hardened pelvis. (05 Mar 2000) |
| funnel-shaped pelvis | A pelvis in which the pelvic inlet dimensions are normal, but the outlet is contracted in the transverse or in both transverse and anteroposterior diameters. (05 Mar 2000) |
| lesser pelvis | The cavity of the pelvis below the brim or superior aperture. Synonym: pelvis minor, pelvis vera, small pelvis, true pelvis. (05 Mar 2000) |
| ligamentum transversum pelvis | <anatomy> The thickened anterior border of the urogenital diaphragm, formed by the fusion of its two fascial layers. Synonym: ligamentum transversum perinei, Krause's ligament, ligamentum transversum pelvis, transverse ligament of pelvis, transverse ligament of perineum. (05 Mar 2000) |
| longitudinal oval pelvis | A pelvis in which the anteroposterior diameter is longer than the transverse. Synonym: longitudinal oval pelvis. (05 Mar 2000) |
| lordotic pelvis | A deformed pelvis associated with lordosis. (05 Mar 2000) |
| Abbe test plate | <equipment> A long, wedge-shaped coverslip about 0.20 mm thick at one end and 0.10 to 0.12 mm at the other end coated chemically with a silver film on which are ruled horizontal lines. at each variation in thickness of 0.01 mm there are vertical lines. By means of oblique illumination and by focusing on different portions of the plate, it is possible to determine the optimum coverslip thickness for any objective and also, for microscopes with drawtubes, the tube length for best objective performance. The approximate freedom from spherical and chromatic aberrations can also be estimated. Small isolated bits of silver near the edges of the lines form good objects for the star test (05 Aug 1998) |
| acetone test | A test for ketonuria; the suspected urine is shaken up with a few drops of sodium nitroprusside, and strong ammonia water is then gently poured over the mixture; if acetone is present, a magenta ring forms at the line of contact; tablets containing sodium nitroprusside and alkali are now more commonly used. (05 Mar 2000) |
| achievement test | A standardised test used to measure acquired learning, e.g., competence in a specific subject area such as reading or arithmetic, in contrast to an intelligence test which is a useful index of potential ability or learning. (05 Mar 2000) |
| acidified serum test | Lysis of the patient's red cells in acidified fresh serum, specific for paroxysmal nocturnal haemoglobinuria. Synonym: Ham's test. (05 Mar 2000) |
| acid loading test | <nephrology> This is a test used in the diagnosis of renal tubular acidosis. The patient takes ammonium chloride capsules for 3 days to acidify the blood (lower blood pH). A sample of the urine and the blood is then collected and the results are interpreted. (27 Sep 1997) |
