| simultagnosia | Inability to recognise multiple elements in a visual presentation, i.e., one object or some elements of a scene can be appreciated but not the display as a whole. Synonym: simultagnosia. Origin: simultaneous + agnosia (05 Mar 2000) |
| simultanagnosia | Inability to recognise multiple elements in a visual presentation, i.e., one object or some elements of a scene can be appreciated but not the display as a whole. Synonym: simultagnosia. Origin: simultaneous + agnosia (05 Mar 2000) |
| simultaneous | Existing or occurring at the same time: coincident, concurrent. (18 Nov 1997) |
| simultaneous contrast | The enhancement of the visual sensation of white when a white object is viewed adjacent to a black object; the black object also appears blacker as a result of the contiguity of white. Adjacent complementary colours also appear brighter; e.g., green appears a brighter green and red a brighter red if these two colours are viewed side by side. (05 Mar 2000) |
| simultaneous hermaphrodite | A type of hermaphrodite which has both male and female organs at the same time and is able to produce both sperm and eggs at the same time. Such an organism is also able to fertilize its eggs with its own sperm (self-fertilization). (09 Oct 1997) |

| SIMV | <abbreviation> Spontaneous intermittent mandatory ventilation, synchronised intermittent mandatory ventilation. (05 Mar 2000) |
| simvastatin | <chemical> A derivative of lovastatin and potent competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme a reductase (hydroxymethylglutaryl CoA reductases), which is the rate-limiting enzyme in cholesterol biosynthesis. It may also interfere with steroid hormone production. Due to the induction of hepatic ldl receptors, it increases breakdown of ldl-cholesterol (lipoproteins, ldl cholesterol). Pharmacological action: anticholesteraemic agents, antilipaemic agents, hydroxymethylglutaryl-CoA reductase inhibitors. (12 Dec 1998) |
