| conjugate | Paired together. In chemistry, this refers to an acid and a base which can convert to each other by the gain or loss of a proton (a hydrogen nucleus), which together are called a conjugate acid-base pair. It can also refer to two liquids in equilibrium with each other. In mycology (the study of fungi), this refers to a dikaryon with two haploid nuclei in it. (09 Oct 1997) |

| conjugate acid | The protonated compound of two compounds that differ in structure only by the presence of the labile proton. (05 Mar 2000) |
| conjugate acid-base pair | In prototonic solvents (e.g., H2O, NH3, acetic acid), two molecular species differing only in the presence or absence of a hydrogen ion (e.g., carbonic acid/bicarbonate ion or ammonium ion/ammonia); the basis of buffer action. (05 Mar 2000) |
| conjugate axis | 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) |
| conjugate deviation of the eyes | Rotation of the eyes equally and simultaneously in the same direction, as occurs normally, a condition in which both eyes are turned to the same side as a result of either paralysis or muscular spasm. (05 Mar 2000) |
| conjugate diameter of pelvic inlet | 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) |
| conjugate diameter of pelvic outlet | The distance from the tip of the coccyx to the lower edge of the pubic symphysis. See: obstetric conjugate of pelvic outlet. Synonym: conjugate diameter of pelvic outlet. (05 Mar 2000) |
| conjugate division | The nuclear division of both haploid nuclei in a dikaryon at the same time (in a dikaryon which has two nuclei). The term is relevant to the biology of fungus. (09 Oct 1997) |
| conjugate foci | <microscopy> In an image-forming system, two fields are said to be conjugate with each other when two or more object fields are simultaneously in focus in a single plane, for example, in Kohler illumination the field diaphragm, specimen and ocular front focal plane are conjugate foci as are the filament, condenser aperture diaphragm, objective back focal plane and ocular front focal plane(when a Bertrand lens is used). (05 Aug 1998) |
| conjugate foramen | A foramen formed by the notches of two bones in apposition. (05 Mar 2000) |
| conjugate ligament | <anatomy> A ligament in some mammals which is the homologue of the intra-articular ligament present in the joints between the heads of the ribs and the vertebrae. Synonym: ligamentum conjugale. (05 Mar 2000) |
| conjugate movement of eyes | Rotation of the two eyes in the same direction. See: version. (05 Mar 2000) |
| conjugate nystagmus | A nystagmus in which the two eyes move simultaneously in the same direction. (05 Mar 2000) |
| conjugate of pelvic inlet | 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) |
| conjugate of pelvic outlet | The distance from the tip of the coccyx to the lower edge of the pubic symphysis. See: obstetric conjugate of pelvic outlet. Synonym: conjugate diameter of pelvic outlet. (05 Mar 2000) |
