| intrinsic colour | <dentistry> The addition of colour pigment within the material of a dental prosthesis. (05 Mar 2000) |
|---|---|
| opponent colour | Pairs of colour that share colour channels in the retina (red-green, blue-yellow, black-white). (05 Mar 2000) |
| echocardiography, doppler, colour | Echocardiography applying the doppler effect, with the superposition of flow information as colours on a gray scale in a real-time image. (12 Dec 1998) |
| tone colour | The distinguishing quality of a sound, by which one may determine its source. Synonym: tone colour. Origin: Fr. (05 Mar 2000) |
| extrinsic colour | Colour applied to the external surface of a dental prosthesis. (05 Mar 2000) |
| eye colour | Colour of the iris. (12 Dec 1998) |
| Young-Helmholtz theory of colour vision | A theory that there are three colour-perceiving elements in the retina: red, green, and blue. Perception of other colours arises from the combined stimulation of these elements; deficiency or absence of any one of these elements results in inability to perceive that colour and a misperception of any other colour of which it forms a part. Synonym: Helmholtz theory of colour vision. (05 Mar 2000) |
| ultrasonography, doppler, colour | Ultrasonography applying the doppler effect, with the superposition of flow information as colours on a gray scale in a real-time image. This type of ultrasonography is well-suited to identifying the location of high-velocity flow (such as in a stenosis) or of mapping the extent of flow in a certain region. (12 Dec 1998) |
| Farnsworth-Munsell colour test | A test for colour perception; the task is to arrange 84 colour disks (in four separate racks of 20-22 disks) in a sequence with minimal separation of hue between adjacent disks. (05 Mar 2000) |
| acute primary haemorrhagic meningoencephalitis | A disease characterised by acute onset of fever, followed by convulsions, delirium, and coma, and associated with perivascular demyelination and haemorrhagic foci in the central nervous system. Synonym: acute primary haemorrhagic meningoencephalitis, Strumpell's disease. (05 Mar 2000) |
| acyclic monoterpene primary alcohol - NADP oxidoreductase | <enzyme> From catmint nepeta racemosa; involved in the biosynthesis of iridoid monoterpenes; oxidises geraniol, nerol, and their 10-hydroxy derivatives in the presence of nadp(+). Registry number: EC 1.1.1.- Synonym: monoterpene primary alcohol - nadp oxidoreductase, ampano (26 Jun 1999) |
| anterior primary division | <anatomy, nerve> The larger, anterolaterally-directed major terminal branch (with the dorsal primary ramus) of all 31 pairs of mixed spinal nerves, formed at the intervertebral foramen. Most ventral primary rami, especially those involved in the innervation of the limbs, participate in the formation of the major nerve plexuses (cervical, brachial, and lumbosacral) and lose their identities. Most in the thoracic region, however, remain separate from adjacent rami to become the intercostal and subcostal nerves. Ventral primary rami provide innervation to the anterolateral body wall and trunk. Nomina Anatomica lists ventral primary rami as "rami ventrales" for each group of spinal nerves: 1) cervical (nervorum cervicalium ), 2) thoracic (nervorum thoracicorum ), 3) lumbar (nervorum lumbalium ), 4) sacral (nervorum sacralium )m, and 5) coccygeal (nervi coccygei ). Synonym: ramus ventralis nervi spinalis, anterior primary division. (05 Mar 2000) |
| aphasia, primary progressive | A type of aphasia appearing gradually and gradually worsening without any major change in other cognitive functions. It is regarded by some authors as a syndrome which may be due to various degenerative diseases of the cerebral cortex (notably alzheimer disease, owing to its frequency), while others see in it an autonomous disease related to a neuropathological process that is distinct from the main degenerative dementias. The principal clinical peculiarity of primary progressive aphasia is that it spares the patient's autonomy for a long time, but ultimately turns into global dementia. (12 Dec 1998) |
| ventral primary rami of cervical spinal nerves | See: ventral primary ramus of spinal nerve. Synonym: rami ventrales nervorum cervicalium. (05 Mar 2000) |
| ventral primary rami of lumbar spinal nerves | See: ventral primary ramus of spinal nerve. Synonym: rami ventrales nervorum lumbalium. (05 Mar 2000) |
