| rcp | reciprocal translocation |
| reciprocal anchorage | Anchorage in which the movement of one or more teeth is balanced against the movement of one or more opposing teeth. (05 Mar 2000) |

| reciprocal arm | A clasp arm or other extension used on a removable partial denture to oppose the action of some other part or parts of the appliance. (05 Mar 2000) |
| reciprocal beat | See: reciprocal rhythm. (05 Mar 2000) |
| reciprocal bigeminy | Paired beats, each pair consisting of an A-V nodal beat followed by a reciprocal beat. (05 Mar 2000) |
| reciprocal forces | In dentistry, force's whereby the resistance of one or more teeth is utilised to move one or more opposing teeth. (05 Mar 2000) |
| reciprocal inhibition | Contraction in a muscle is accompanied by a loss of tone or by relaxation in the antagonistic muscle. Synonym: reciprocal inhibition. (05 Mar 2000) |
| reciprocal innervation | Contraction in a muscle is accompanied by a loss of tone or by relaxation in the antagonistic muscle. Synonym: reciprocal inhibition. (05 Mar 2000) |
| reciprocal rhythm | A cardiac arrhythmia in which the impulse arising in the A-V junction descends to and activates the ventricles on one intrajunctional pathway and simultaneously ascends toward the atria in parallel pathways; before reaching the atria, however, the impulse is reflected downward and again activates the ventricles, producing an echo or reciprocal beat; recognised in the electrocardiogram by the presence of an inverted P wave in lead aVF and usually II sandwiched between two ventricular complexes aberrantly, both of which may be normal or one of which may be conducted. (05 Mar 2000) |
| reciprocal transfusion | An attempt to confer immunity by transfusing blood taken from a donor into a receiver suffering from the same affection, the balance being maintained by transfusing an equal amount from the receiver to the donor. (05 Mar 2000) |
| reciprocal translocation | Translocation without demonstrable loss of genetic material. (05 Mar 2000) |
| reciprocal treanslocation | Mutual exchange of chromosome segments between two nonhomologous chromosomes (chromosomes that do not belong to the same pair). (12 Dec 1998) |
| reversed reciprocal rhythm | A cardiac arrhythmia in which a normal sinus impulse, before reaching the ventricles, is reflected backward to the atria; thus in the electrocardiogram a ventricular complex is sandwiched between a normal sinus P wave and a retrograde P wave; if the dysrhythmia continues, subsequent cycles are similar to those of reciprocating rhythm. (05 Mar 2000) |
| double-reciprocal plot | <statistics> A graph made to analyse how fast an enzyme can convert its substrate into its product, depending on how much substrate is present (its concentration) and to determine its maximum speed (after which the enzyme does not get any faster no matter how high the concentration of substrate gets), called Vmax. It is a plot of 1/v versus 1/[S], where v=rate of product formation and [S]=the concentration of the substrate. Synonym: Lineweaver-Burk plot, Woolf-Lineweaver-Burk plot. (05 Mar 2000) |
| law of reciprocal proportions | The relative weights in which two substances form a chemical union singly with a third are the same as, or simple multiples of, those in which they unite with each other; a corollary of the law of definite proportions. Synonym: law of multiple proportions. (05 Mar 2000) |
