|---|---|
| apertura pelvis inferior | The lower opening of the true pelvis, bounded anteriorly by the pubic arch, laterally by the rami of the ischium and the sacrotuberous ligament on either side, and posteriorly by these ligaments and the tip of the coccyx. Synonym: apertura pelvis inferior, apertura pelvis minoris, fourth parallel pelvic plane, pelvic outlet, pelvic plane of outlet, plane of outlet. (05 Mar 2000) |
| apertura pelvis minoris | The lower opening of the true pelvis, bounded anteriorly by the pubic arch, laterally by the rami of the ischium and the sacrotuberous ligament on either side, and posteriorly by these ligaments and the tip of the coccyx. Synonym: apertura pelvis inferior, apertura pelvis minoris, fourth parallel pelvic plane, pelvic outlet, pelvic plane of outlet, plane of outlet. (05 Mar 2000) |
| apertura pelvis superior | The upper opening of the true pelvis, bounded anteriorly by the pubic symphysis and the pubic crest on either side, laterally by the iliopectineal lines, and posteriorly by the promontory of the sacrum. Synonym: apertura pelvis superior, aditus pelvis, first parallel pelvic plane, pelvic brim, pelvic inlet, pelvic plane of inlet, plane of inlet. (05 Mar 2000) |
| arcus tendineus fasciae pelvis | A linear thickening of the superior fascia of the pelvic diaphragm extending posteriorly from the body of the pubis alongside the bladder (and vagina in the female) and giving attachment to the supporting ligaments of the pelvic viscera. Synonym: arcus tendineus fasciae pelvis. (05 Mar 2000) |
| assimilation pelvis | A deformity in which the transverse processes of the last lumbar vertebra are fused with the sacrum, or the last sacral with the first coccygeal body. (05 Mar 2000) |
| axis pelvis | A hypothetical curved line joining the centre point of each of the four planes of the pelvis, marking the centre of the pelvic cavity at every level. Synonym: axis pelvis, plane of pelvic canal. (05 Mar 2000) |
| beaked pelvis | A pelvic deformity in osteomalacia; the pressure of the trunk on the sacrum and lateral pressure of the femoral heads produce a pelvic aperture that is three-cornered or has the shape of a heart or cloverleaf, while the pubic bone becomes beak-shaped. Synonym: beaked pelvis, rostrate pelvis. (05 Mar 2000) |
| brachypellic pelvis | A pelvis in which the transverse diameter is more than 1 cm longer but less than 3 cm longer than the anteroposterior diameter. Synonym: transverse oval pelvis. (05 Mar 2000) |
| caoutchouc pelvis | In osteomalacia, a pelvis in which the bones are still soft. Synonym: rubber pelvis. (05 Mar 2000) |
| rachitic pelvis | A contracted and deformed pelvis, most commonly a flat pelvis, occurring from rachitic softening of the bones in early life. (05 Mar 2000) |
| masculine pelvis | A pelvis justo minor in which the bones are large and heavy, a slight degree of funnel-shaped pelvis in the woman, in which the shape approximates that of the male pelvis. (05 Mar 2000) |
| cavitas pelvis | The space bounded at the sides by the bones of the pelvis, above by the superior aperture of the pelvis, and below by the pelvic diaphragm; it contains the pelvic viscera. Synonym: cavitas pelvis, cavum pelvis. (05 Mar 2000) |
| cavum pelvis | The space bounded at the sides by the bones of the pelvis, above by the superior aperture of the pelvis, and below by the pelvic diaphragm; it contains the pelvic viscera. Synonym: cavitas pelvis, cavum pelvis. (05 Mar 2000) |
| renal pelvis | <anatomy> The area at the centre of the kidney. Urine collects here and is funneled into the ureter. (12 Dec 1998) |
