| silver-ammoniacal silver stain | <technique> A stain for the acid protein component of nucleolar regions which are active or which were transcriptionally active in the preceding interphase; uses silver nitrate, ammoniacal silver, and formalin. Synonym: Ag-AS stain. (05 Mar 2000) |

| antipodal cone | The set of astral rays of a dividing cell extending from the centriole in a direction opposite to the equatorial plate. (05 Mar 2000) |
| arterial cone | The left or anterosuperior, smooth-walled portion of the cavity of the right ventricle of the heart, which begins at the supraventricular crest and terminates in the pulmonary trunk. Synonym: arterial cone, pulmonary cone, pulmonary conus. (05 Mar 2000) |
| blue cone monochromatism | Impaired, but not absent, colour vision with less severely reduced visual acuity than in complete achromatopsia; inherited as an autosomal recessive or as an X-linked disorder (blue cone monochromism; pi cone monochromatism ). (05 Mar 2000) |
| Rambourg's periodic acid-chromic methenamine-silver stain | <technique> A stain for glycoproteins, used with an electron microscope, adapted from the Gomori-Jones periodic acid-methenamine-silver stain; it produces silver deposits in mature saccules of the Golgi apparatus, lysosomal vesicles, cell coat, and basement membranes. (05 Mar 2000) |
| Masson-Fontana ammoniacal silver stain | <technique> A stain used to demonstrate melanin and argentaffin granules. Synonym: Fontana-Masson silver stain. (05 Mar 2000) |

| rep-silver | Money anciently paid by servile tenants to their lord, in lieu of the customary service of reaping his corn or grain. See: Reap. Source: Websters Dictionary (01 Mar 1998) |
| medullary cone | The tapering lower extremity of the spinal cord. Synonym: conus medullaris. (05 Mar 2000) |
| retinal cone | <ophthalmology, physiology> One of the two photoreceptor cell types in the vertebrate retina. In cones the photopigment is in invaginations of the cell membrane of the outer segment. Cones are less sensitive to light than rods, and are differentially sensitive to particular wavelengths of light and therefore important for colour vision. They provide vision with higher spatial and temporal acuity, and it is the combination of signals from cones with different pigments that facilitates colour vision. There are three types of cones, each type sensitive to red, green or blue. Present in large numbers in the fovea. (03 Jul 1999) |
| Gomori-Jones periodic acid-methenamine-silver stain | <technique> A staining method using methenamine silver, periodic acid, gold chloride, haematoxylin, and eosin to delineate basement membrane, reticulin, collagen, and nuclei; used in renal histopathology. See: Rambourg's periodic acid-chromic methenamine-silver stain. (05 Mar 2000) |
| Gomori's methenamine-silver stain | <technique> Techniques for 1) argentaffin cells: a method using a methenamine-silver solution in combination with gold chloride, sodium thiosulphate, and safranin O; argentaffin granules appear brown-black against a green background; 2) urates: warm sections are treated directly with a hot methenamine-silver solution to produce a blackening of urates; 3) fungi: see Grocott-Gomori methenamine-silver stain; 4) melanin, which reduces silver nitrate. (05 Mar 2000) |
| Gomori's silver impregnation stain | <technique> A reliable method for reticulin, as an aid in the diagnosis of neoplasm and early cirrhosis of the liver; the staining solution employs silver nitrate, potassium hydroxide, and ammonia water carefully prepared to avoid having silver precipitate. (05 Mar 2000) |
| Grocott-Gomori methenamine-silver stain | <technique> A modification of Gomori's methenamine-silver stain for fungi in which sections are pretreated with chromic acid before addition of the methenamine-silver solution and then counterstained with light green to demonstrate black-brown fungi against a pale green background. (05 Mar 2000) |
| 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) |
| silver cone m. |
in root canal therapy, a method of filling the canal in which a prefitted silver point is sealed into the canal apex and irregularities in the canal that are not sealed with the point are obliterated by gutta-percha through lateral condensation or segmentation, or by a root canal paste or sealer.
