inversion

 [in-ver´zhun]
1. a turning inward, inside out, or other reversal of the normal relation of a part.
2. in psychiatry, a term used by Freud for homosexuality.
3. a chromosomal aberration due to the inverted reunion of the middle segment after breakage of a chromosome at two points, resulting in a change in sequence of genes or nucleotides.

in·ver·sion

(in-ver'zhŭn),
1. A turning inward, upside down, or in any direction contrary to the existing one.
2. Conversion of a disaccharide or polysaccharide by hydrolysis into a monosaccharide; specifically, the hydrolysis of sucrose to d-glucose and d-fructose; so called because of the change in optic rotation.
3. Alteration of a DNA molecule made by removing a fragment, reversing its orientation, and putting it back into place.
4. Heat-induced transition of silica, in which the quartz tridymite or cristobalite changes its physical properties as to thermal expansion.
5. Conversion of a chiral center into its mirror image.

n.
1.
a. The act of inverting.
b. The state of being inverted.
2. Psychology In early psychology, behavior or attitudes in an individual considered typical of the opposite sex, including sexual attraction to members of one's own sex. No longer in technical use.
3. Chemistry Conversion of a substance in which the direction of optical rotation is reversed, from the dextrorotatory to the levorotatory or from the levorotatory to the dextrorotatory form.
4. Genetics A chromosomal rearrangement in which a segment of the chromosome breaks off and reattaches in the reverse direction.

Orthopedics A frontal plane movement of the foot, where the plantar surface is tilted to face the midline of the body or the medial sagittal plane; the axis of motion lies on the sagittal and transverse planes; a fixed inverted position is referred to as a varus deformity
