| crossing over | <genetics, molecular biology> The breaking during meiosis of one maternal and one paternal chromosome, the reciprocal exchange of corresponding sections of DNA along pairs of homologous chromosomes by symmetrical breakage and crosswise rejoining of the chromosomes. This results in the transfer of a block of genes from each chromosome to its homologue. In contrast to genetic recombination, which is a phenotypic phenomenon, crossing-over is genotypic. Any even number of crossing-overs between two loci will cancel out phenotypically and no recombination will occur. Recombination can result from DNA exchange of alleles between between homologous chromatids in meiosis, giving rise to chiasmata. Compare: recombination. (10 Nov 1998) |
| somatic crossing-over | Crossing-over that occurs during the mitosis of somatic cells, in contrast to that which occurs in meiosis. (05 Mar 2000) |
| unequal crossing over | <cell biology> Crossing over between homologous chromosomes that are not precisely paired, resulting in nonreciprocal exchange of material and chromosomes of unequal length. Favoured in regions containing tandemly repeated sequences. (18 Nov 1997) |
| uneven crossing-over | Unequal crossing-over, crossing-over that happens when the breaks do not occur at precisely homologous points in two chromatid strands, and hence results in localised duplication of genetic material in one chromatid and complementary deletion in the other. (05 Mar 2000) |
| four-strand crossing over | Crossing over with both strands of DNA from each sister chromatid, so that both strands from one chromatid are exchanged for both strands on the other. This is different from the usual case where only one of the two DNA strands on one sister chromatid is exchanged for the one matching strand (of the two strands) on the other sister chromatid.

| arteriolovenular bridge | The largest capillary connecting arteriole to venule. (05 Mar 2000) |
| bridge | 1. To build a bridge or bridges on or over; as, to bridge a river. "Their simple engineering bridged with felled trees the streams which could not be forded." (Palfrey) 2. To open or make a passage, as by a bridge. "Xerxes . . . Over Hellespont Bridging his way, Europe with Asia joined." (Milton) 3. To find a way of getting over, as a difficulty; generally with over. Origin: Bridged; Bridging. 1. A structure, usually of wood, stone, brick, or iron, erected over a river or other water course, or over a chasm, railroad, etc, to make a passageway from one bank to the other. 2. Anything supported at the ends, which serves to keep some other thing from resting upon the object spanned, as in engraving, watchmaking, etc, or which forms a platform or staging over which something passes or is conveyed. 3. The small arch or bar at right angles to the strings of a violin, guitar, etc, serving of raise them and transmit their vibrations to the body of the instrument. 4. <physics> A device to measure the resistance of a wire or other conductor forming part of an electric circuit. 5. A low wall or vertical partition in the fire chamber of a furnace, for deflecting flame, etc.; usually called a bridge wall. Aqueduct bridge. See Aqueduct. Asses' bridge, Bascule bridge, Bateau bridge. See Ass, Bascule, Bateau. Bridge of a steamer, a narrow platform across the deck, above the rail, for the convenience of the officer in charge of the ship; in paddlewheel vessels it connects the paddle boxes. Bridge of the nose, the upper, bony part of the nose. Cantalever bridge. See Cantalever. Draw bridge. See Drawbridge. Flying bridge, a temporary bridge suspended or floating, as for the passage of armies; also, a floating structure connected by a cable with an anchor or pier up stream, and made to pass from bank to bank by the action of the current or other means. Girder bridge or Truss bridge, a bridge formed by girders, or by trusses resting upon abutments or piers. Lattice bridge, a bridge formed by lattice girders. Pontoon bridge, Ponton bridge. See Pontoon. Skew bridge, a bridge built obliquely from bank to bank, as sometimes required in railway engineering. Suspension bridge. See Suspension. Trestle bridge, a bridge formed of a series of short, simple girders resting on trestles. Tubular bridge, a bridge in the form of a hollow trunk or rectangular tube, with cellular walls made of iron plates riveted together, as the Britannia bridge over the Menai Strait, and the Victoria bridge at Montreal. <physics> Wheatstone's bridge, a device for the measurement of resistances, so called because the balance between the resistances to be measured is indicated by the absence of a current in a certain wire forming a bridge or connection between two points of the apparatus; invented by Sir Charles Wheatstone. Origin: OE. Brig, brigge, brug, brugge, AS. Brycg, bricg; akin to Fries. Bregge, D. Brug, OHG. Bruccu, G. Brucke, Icel. Bryggja pier, bridge, Sw. Brygga, Dan. Brygge, and prob. Icel. Br bridge, Sw. & Dan. Bro bridge, pavement, and possibly to E. Brow. Source: Websters Dictionary (01 Mar 1998) |
| bridge corpuscle | <cell biology> Specialised cell junction characteristic of epithelia into which intermediate filaments (tonofilaments of cytokeratin) are inserted. The gap between plasma membranes is of the order of 25-30nm and the intercellular space has a medial band of electron dense material. Desmosomes are particularly conspicuous in tissues such as skin that have to withstand mechanical stress. Origin: Gr. Soma = body (18 Nov 1997) |
| cantilever bridge | A fixed partial bridge denture in which the pontic is retained only on one side by an abutment tooth. Synonym: extension bridge. (05 Mar 2000) |
| Gaskell's bridge | The bundle of modified cardiac muscle fibres that begins at the atrioventricular node as the trunk of the atrioventricular bundle and passes through the right atrioventricular fibrous ring to the membranous part of the interventricular septum where the trunk divides into two branches, the right crus of the atrioventricular bundle and the left crus of the atrioventricular bundle; the two crura ramify in the subendocardium of their respective ventricles. Synonym: fasciculus atrioventricularis, atrioventricular band, Gaskell's bridge, His' band, His' bundle, bundle of His, Keith's bundle, Kent's bundle, Kent-His bundle, ventriculonector. (05 Mar 2000) |
| removable bridge | A partial denture which supplies teeth and associated structures on a partially edentulous jaw, and which can be readily removed from the mouth. Synonym: removable bridge. (05 Mar 2000) |
| wheatstone's bridge | <physics> See Bridge. Source: Websters Dictionary (01 Mar 1998) |
| myocardial bridge | A bridge of cardiac muscle fibres extending over the epicardial aspect of a coronary artery; this finding, in cases of sudden unexpected death, has led to speculation that cardiac contraction during exertion could constrict the coronary artery. (05 Mar 2000) |
| cystine bridge | A disulfide linkage between two cysteinyl residues in a poly-or oligopeptide or in a protein, any disulfide linkage between any thiol-containing moieties of a larger molecule. Synonym: cystine bridge. (05 Mar 2000) |
