| internal conjugate | Distance from the promontory of the sacrum to the upper posterior edge of the pubic symphysis. Synonym: anteroposterior diameter of the pelvic inlet, conjugata vera, conjugate axis, conjugate diameter of pelvic inlet, diameter mediana, internal conjugate, true conjugate. (05 Mar 2000) |
|---|---|
| obstetric conjugate | The diameter that represents the shortest diameter through which the head must pass in descending into the superior strait and measures, by means of X-ray, the distance from the promontory of the sacrum to a point on the inner surface of the symphysis a few millimeters below its upper margin. Synonym: obstetric conjugate diameter. (05 Mar 2000) |

Synonym: obstetric conjugate diameter. (05 Mar 2000) |
| obstetric conjugate of pelvic outlet | The conjugate of the pelvic outlet lengthened by the posterior displacement of the coccyx. (05 Mar 2000) |
| effective conjugate | The internal conjugate measured from the nearest lumbar vertebra to the symphysis, in spondylolisthesis. Synonym: false conjugate. (05 Mar 2000) |
| true conjugate | Distance from the promontory of the sacrum to the upper posterior edge of the pubic symphysis. Synonym: anteroposterior diameter of the pelvic inlet, conjugata vera, conjugate axis, conjugate diameter of pelvic inlet, diameter mediana, internal conjugate, true conjugate. (05 Mar 2000) |
| external conjugate | The distance in a straight line between the depression under the last spinous process of the lumbar vertebrae and the upper edge of the pubic symphysis. Synonym: Baudelocque's diameter, external conjugate diameter. (05 Mar 2000) |
| external conjugate diameter | The distance in a straight line between the depression under the last spinous process of the lumbar vertebrae and the upper edge of the pubic symphysis. Synonym: Baudelocque's diameter, external conjugate diameter. (05 Mar 2000) |
| false conjugate | The anteroposterior dimension of the inlet that measures the clinical distance from the promontory of the sacrum to the lower margin of the symphysis pubica. Synonym: conjugata diagonalis, diagonal conjugate diameter, false conjugate. (05 Mar 2000) |
| folic acid conjugate | A folate with three molecules of glutamic acid (pteropterin) instead of one, or with seven (pteroylheptaglutamic acid or vitamin Bc conjugate). (05 Mar 2000) |
| receptors, cytoplasmic and nuclear | Proteins in the cytoplasm or nucleus that specifically bind signalling molecules and trigger changes which influence the behaviour of cells. The major groups are the steroid hormone receptors, which usually are found in the cytoplasm, and the thyroid hormone receptors, which usually are found in the nucleus. Receptors, unlike enzymes, generally do not catalyze chemical changes in their ligands. (12 Dec 1998) |
| Pelger-Huet nuclear anomaly | Congenital inhibition of lobulation in the nuclei of neutrophilic leukocytes; most cells present band or bilobulate appearance, and only an occasional cell is trilobed; it is not associated with disease, but may be confused with leukocyte "shift to left"; autosomal dominant inheritance. (05 Mar 2000) |
| ribonucleoproteins, small nuclear | Highly conserved nuclear RNA-protein complexes that function in RNA processing in the nucleus, including pre-mRNA splicing and pre-mRNA 3'-end processing in the nucleoplasm. The u3 snrnp is localised in the nucleolus, where it aligns into base pairs with the 28s rrna precursor in a still unidentified region and functions in pre-rrna processing. The u7 snrnp aligns into base pairs with a conserved sequence in the 3'-end of histone pre-mRNA and is an essential cofactor for the cleavage that creates the mature nonadenylated 3'-end. (12 Dec 1998) |
| RNA, heterogeneous nuclear | Nuclear nonribosomal RNA larger than about 1000 nucleotides, the mass of which is rapidly synthesised and degraded within the cell nucleus. Some heterogeneous nuclear RNA may be a precursor to mRNA. However, the great bulk of total hnrna hybridises with nuclear DNA rather than with mRNA. (12 Dec 1998) |
| RNA, nuclear | RNA molecules found in the nucleus either associated with chromosomes or in the nucleoplasm. (12 Dec 1998) |
