| annular stop | <microscopy> The opaque ring-shaped stop with a small central opening usually placed in the objective back focal plane to provide dispersion staining. (05 Aug 1998) |
|---|---|
| central stop | <microscopy> An opaque disk placed in the ring carrier or diaphragm carrier of the substage apparatus. It excludes the central rays and is used for dark field work at low magnification. Variable stops can be contracted or expanded as desired. (05 Aug 1998) |
| stop | <dentistry> A bend or auxiliary attachment placed on a wire to limit the archwire from sliding or moving in the bracket slot of the bracket. (08 Jan 1998) |
| stop codon | <molecular biology> The three codons, UAA known as ochre, UAG as amber and UGA as opal, that do not code for an amino acid but act as signals for the termination of protein synthesis. They are not represented by any tRNA and termination is catalysed by protein release factors. There are two release factors in E. Coli, RF1 recognises UAA and UAG, RF2 recognises UAA and UGA. Eukaryotes have a single GTP requiring factor, eRF. See: ochre suppressor, amber suppressor. (13 Jan 1998) |
| stop-needle | A surgical needle, with the eye at the tip, the shank of which has a projecting shelf to arrest the needle when it has passed the desired distance through the tissues. (05 Mar 2000) |
| stop-speculum | A dilating speculum, as a speculum of the eyelids, which is provided with a catch to prevent its being opened too wide. (05 Mar 2000) |
| dark field stop | <microscopy> A central stop for obtaining a dark field effect for low-power objectives. It is customarily used with a high numerical aperture, bright field condenser. (05 Aug 1998) |
| quick-stop mutant | A bacterial mutant that ceases replication immediately when the temperature reaches a certain level. Compare: temperature-sensitive mutant. (05 Mar 2000) |
| Krueger instrument stop | A mechanical device limiting the insertion of a root canal instrument into a canal. (05 Mar 2000) |
| bar clasp | A clasp whose arms are bar-type extensions from major connectors or from within the denture base; the arms pass adjacent to the soft tissues and approach the point of contact on the tooth in a gingivo-occlusal direction, a clasp consisting of two or more separate arms located opposite to each other on the tooth; the bar arms arise from the framework or from a connector and may traverse the soft tissue; one arm (bar), the retentive arm, usually terminates in the infrabulge (gingival convergence) area of the tooth; the other, the reciprocal arm, usually terminates on the suprabulge (occlusal convergence) area. Synonym: Roach clasp. (05 Mar 2000) |
| bar clasp arm | A clasp arm which has its origin in the denture base or major connector; it consists of the arm which traverses but does not contact the gingival structures, and a terminal end which approaches its contact with the tooth in a gingivo-occlusal direction. (05 Mar 2000) |
| retentive circumferential clasp arm | An arm that is flexible and engages the infrabulge at the terminal end of the arm. (05 Mar 2000) |
| Roach clasp | A clasp whose arms are bar-type extensions from major connectors or from within the denture base; the arms pass adjacent to the soft tissues and approach the point of contact on the tooth in a gingivo-occlusal direction, a clasp consisting of two or more separate arms located opposite to each other on the tooth; the bar arms arise from the framework or from a connector and may traverse the soft tissue; one arm (bar), the retentive arm, usually terminates in the infrabulge (gingival convergence) area of the tooth; the other, the reciprocal arm, usually terminates on the suprabulge (occlusal convergence) area. Synonym: Roach clasp. (05 Mar 2000) |
| circumferential clasp | A clasp that encircles more than 180 |
| circumferential clasp arm | A clasp arm which has its origin in a minor connector and which follows the contour of the tooth approximately in a plane perpendicular to the path of insertion of the partial denture. (05 Mar 2000) |
