| paracentric inversion | A basic type of chromosome rearrangement. A segment that does not include the centromere (and so is paracentric) has been snipped out of a chromosome, turned through 180 degrees (inverted), and inserted right back into its original location in chromosome. (12 Dec 1998) |

| visceral inversion | A transposition of the viscera, e.g., the liver developing on the left side or the heart on the right. Synonym: visceral inversion. (05 Mar 2000) |
| pericentric inversion | <cell biology, genetics> Chromosomal inversion in which the region that is inverted includes the kinetochore. (18 Nov 1997) |
| short TI inversion recovery | An inversion recovery sequence that uses a short inversion time, about 100 ms., between 180 |
| inversion | 1. The act of inverting, or turning over or backward, or the state of being inverted. 2. <mathematics> A change in the order of the terms of a proportion, so that the second takes the place of the first, and the fourth of the third. 3. <genetics> An aberration in which a chromosomal segment is deleted and reinserted in the same place but turned 180 degrees from its original orientation, so that the gene sequence for the segment is reversed with respect to that of the rest of the chromosome. 4. <geometry> A peculiar method of transformation, in which a figure is replaced by its inverse figure. Propositions that are true for the original figure thus furnish new propositions that are true in the inverse figure. See Inverse figures, under Inverse. 5. Said of intervals, when the lower tone is placed an octave higher, so that fifths become fourths, thirds sixths, etc. Said of a chord, when one of its notes, other than its root, is made the bass. 6. <geology> The folding back of strata upon themselves, as by upheaval, in such a manner that the order of succession appears to be reversed. 7. <chemistry> The act or process by which cane sugar (sucrose), under the action of heat and acids or ferments (as diastase), is broken or split up into grape sugar (dextrose), and fruit sugar (levulose); also, less properly, the process by which starch is converted into grape sugar (dextrose). The terms invert and inversion, in this sense, owe their meaning to the fact that the plane of polarization of light, which is rotated to the right by cane sugar, is turned toward the left by levulose. See: invert. Origin: L. Inversio: cf. F. Inversion. Source: Websters Dictionary (04 Jul 1999) |
| inversion heterozygote | <genetics> Individual in which one chromosome contains an inversion whereas the homologous chromosome does not. (18 Nov 1997) |
| inversion of chromosomes | A chromosome aberration resulting from a double break in a segment of the chromosome, with end for end rotation of the fragment between the fracture lines, and refusion of the fragments; this results in reversal of the order of genes in that segment. (05 Mar 2000) |
| inversion of the uterus | A turning of the uterus inside out, usually following childbirth. (05 Mar 2000) |
| inversion recovery | A magnetic resonance pulse sequence in which a series of 180 |
| uterine inversion | A turning of the uterus inside out, whereby the fundus is forced through the cervix and protrudes into or outside of the vagina. (12 Dec 1998) |
| acid wave | A temporary increase in the acidity of the urine occurring during fasting. Synonym: acid wave. (05 Mar 2000) |
| alkaline wave | A period of urinary neutrality or even alkalinity after meals due to withdrawal of hydrogen ion for the purpose of secretion of the highly acid gastric juice. Synonym: alkaline wave. (05 Mar 2000) |
| alpha wave | Brain waves in the encephalogram which have a frequency of 8 to 13 per second. They are typical of the normal person awake and in a quiet resting state, and occur principally in the occipital region. (12 Dec 1998) |
| arterial wave | A wave in the jugular phlebogram due to transmission of carotid artery pulsation. B wave, the initial positive deflection in the electroretinogram, possibly arising from the inner nuclear layer of the retina. (05 Mar 2000) |
| A wave | The initial negative deflection in the electroretinogram, presumably reflecting retinal photoreceptor activity, an atrial deflection in an electrocardiogram recorded from within the atrium of the heart, the first positive deflection of the atrial and venous pulses due to atrial systole.
