| life tables | Summarizing techniques used to describe the pattern of mortality and survival in populations. These methods can be applied to the study not only of death, but also of any defined endpoint such as the onset of disease or the occurrence of disease complications. (12 Dec 1998) |
| Stilling, Benedict | <person> German anatomist, 1810-1879. See: Stilling's canal, Stilling's column, Stilling's nucleus, Stilling's raphe, Stilling's gelatinous substance. (05 Mar 2000) |
| Stilling, Jakob | <person> German ophthalmologist, 1842-1915. See: Stilling colour tables. (05 Mar 2000) |
| Stilling's canal | A minute canal running through the vitreous from the discus nervi optici to the lens, containing in foetal life a prolongation of the central artery of the retina, the hyaloid artery. See: vitreous, hyaloid artery. Synonym: canalis hyaloideus, central canal of the vitreous, Cloquet's canal, Stilling's canal. (05 Mar 2000) |
| Stilling's column | A column of large neurons located in the base of the posterior gray column of the spinal cord, extending from the first thoracic through the second lumbar segment; it gives rise to the dorsal spinocerebellar tract of the same side. Synonym: nucleus thoracicus, Clarke's column, Clarke's nucleus, dorsal nucleus, nucleus dorsalis, Stilling's column, Stilling's nucleus. (05 Mar 2000) |
| Stilling's gelatinous substance | The central gray matter of the spinal cord surrounding the central canal. Synonym: substantia intermedia centralis et lateralis, anterior gray column, Stilling's gelatinous substance, substantia gelatinosa centralis. (05 Mar 2000) |
| Stilling's nucleus | A column of large neurons located in the base of the posterior gray column of the spinal cord, extending from the first thoracic through the second lumbar segment; it gives rise to the dorsal spinocerebellar tract of the same side. Synonym: nucleus thoracicus, Clarke's column, Clarke's nucleus, dorsal nucleus, nucleus dorsalis, Stilling's column, Stilling's nucleus. (05 Mar 2000) |
| Stilling's raphe | The transverse interdigitations of fibre bundles across the anterior median fissure of the medulla oblongata at the decussation of the pyramidal tracts. (05 Mar 2000) |
| blue white colour selection | <molecular biology, procedure> Method for identifying bacterial clones containing plasmids with inserts. Many modern vectors have their polycloning site within a part of the LacZ gene encoding _ galactosidase, which provides _ complementation in an appropriate mutant E. Coli strain. This means that a re ligated (empty) vector will produce blue colonies when grown on plates containing IPTG and X gal, but colonies with a substantial insert in their plasmid's polycloning site are unable to produce functional _ galactosidase and so produce white colonies. (16 Dec 1997) |
| colour | 1. That aspect of the appearance of objects and light sources that may be specified as to hue, lightness (brightness), and saturation. 2. That portion of the visible (370-760 nm) electromagnetic spectrum specified as to wavelength, luminosity, and purity. Origin: L. (05 Mar 2000) |
| colour aberration | When using white light through a lens system, it is inevitable that different wave lengths (colours) are brought to a focus at slightly different points. As a consequence, there are chromatic aberations in the image, good microscope objectives are therefore corrected for this at two wave lengths (achromats) or at three wave lengths (apochromats), as well as for spherical aberration. (18 Nov 1997) |
| colour agnosia | The inability to name or identify specific colours by sight; caused by lesions of the dominant occipital and temporal lobes. (05 Mar 2000) |
| colour blindness | A sex-linked inherited condition where there is an inability to distinguish colours. Very few women are colour blind, but up to 10% of all men have some degree of colour blindness. The most common for is red-green colour blindness. The second most common is blue-yellow. Inheritance: sex-linked (X chromosome). (27 Sep 1997) |
| colour constancy | Unchanging perception of the colour of an object despite changes in lighting or viewing conditions. (05 Mar 2000) |
