| silver staining | The use of silver, usually silver nitrate, as a reagent for producing contrast or colouration in tissue specimens. (12 Dec 1998) |
|---|---|
| silver sulfadiazine | <chemical> Antibacterial used topically in burn therapy. Pharmacological action: anti-infective agents, local. Chemical name: Silver, (4-amino-N-2-pyrimidinylbenzenesulfonamidato-NN,O1)- (12 Dec 1998) |
| silver-tin alloy | Any alloy of silver and tin; commonly 3 parts Ag and 1 part Sn, forming Ag3Sn, the chief intermetallic compound in dental amalgam. (05 Mar 2000) |
| nerve growth cone | <cell biology> A specialised region at the tip of a growing neurite that is responsible for sensing the local environment and moving toward the neuron's target cell. Growth cones are hand shaped, with several long filopodia that differentially adhere to surfaces in the embryo. Growth cones can be sensitive to several guidance cues, for example: surface adhesiveness, growth factors, neurotransmitters and electric fields (galvanotropism). (18 Nov 1997) |
| strong silver protein | A compound of sil'ver and protein containing not less than 7.5 and not more than 8.5% of sil'ver; used externally as an antiseptic, devoid of astringent and nearly so of irritant properties. (05 Mar 2000) |
| drift cyclotron loss cone instabilities | (DCLC) This is an electrostatic microinstability (frequencies at harmonics of the ion cyclotron frequency) which is of major concern in small mirror devices. Mode is driven by radial gradients in the electron density, and causes loss of ions due to non-conservation of magnetic moment (see adiabatic invariant) as they interact with the mode, and are dispersed in velocity space into the loss cone. Stabilisation is accomplished by increasing the plasma size and by partially filling the loss cone with a continuous extermal warm plasma stream. (09 Oct 1997) |
| icecream cone | <radiology> Ball of icecream head of malleus, cone body of incus (12 Dec 1998) |
| implantation cone | <cell biology> Tapering region between a neuron's cell body and its axon. This region is responsible for summating the graded inputs from the dendrites and producing action potentials if the threshold is exceeded. (12 Mar 1998) |
| inverted cone bur | A rotary cutting instrument in the shape of a truncated cone with the smaller end attached to the shaft; generally used for entering carious pits or creating undercuts in cavity preparations. (05 Mar 2000) |
| ocular cone | The cone of light in the interior of the eyeball with the base formed by the rays entering through the pupil and the apex focused on the retina. (05 Mar 2000) |
| outer cone fibre | Located between the inner segment and the cell body. (05 Mar 2000) |
| theca interna cone | The conical thickening of thecal cells of an ovarian follicle with its apex pointed toward the surface. (05 Mar 2000) |
| elastic cone | Thicker lower portion of the elastic membrane of the larynx, extending between the cricoid cartilage and the vocal ligaments, the latter actually being a thickening of the free, superior margin of the conus elasticus. Synonym: cricovocal membrane, elastic cone. Synonym: cricothyroid ligament. (05 Mar 2000) |
| toughened silver nitrate | Silver nitrate mixed with silver chloride and allowed to dry. Usually applied to the ends of small wooden applicator sticks or made available as pencils. These are used after wetting as a caustic chemical for the removal of warts. Synonym: fused silver nitrate, lunar caustic. (05 Mar 2000) |
| twin cone | Two retinal cone's fused together. (05 Mar 2000) |
