| membrana propria ductus saemicircularis | The meshwork of connective tissue fibres between the saemicircular duct and the bony saemicircular canal; it encloses the perilymph in its spaces. Synonym: membrana propria ductus saemicircularis. (05 Mar 2000) |

| tunica propria | <anatomy> The special envelope of a part as distinguished from the peritoneal or other investment common to several parts. (05 Mar 2000) |

| tunica propria lienis | The fibrous capsule of the spleen, containing collagen, elastic fibres, and smooth muscle. Synonym: tunica fibrosa splenis, tunica fibrosa lienis, capsula lienis, tunica propria lienis. (05 Mar 2000) |

| substantia | Synonym: substance. Origin: L. (05 Mar 2000) |
| substantia adamantina | <dentistry> A hard ceramic which covers the exposed part of your teeth. (08 Jan 1998) |
| substantia alba | <anatomy> Brain tissue composed of myelin-coated nerve cell fibres. White matter carries information between the nerve cells in the brain and spinal cord. The inner portion of the cerebrum is composed of white matter. See: grey matter. (13 Nov 1997) |
| substantia basophilia | The material consisting of granular endoplasmic reticulum and ribosomes that occurs in nerve cell bodies and dendrites. Synonym: basophil substance, basophilic substance, chromophil substance, Nissl bodies, Nissl granules, substantia basophilia, tigroid bodies, tigroid substance. (05 Mar 2000) |
| substantia cinerea | The cortex of the brain which contains nerve cell bodies. The gray matter is in contrast to the white matter, the part of the brain that contains myelinated nerve fibres. The gray matter is so named because it in fact appears gray. The white matter is white because that is the colour of myelin, the insulation covering the nerve fibres. In the mysterious affair at styles (1920), agatha christie first quoted the fictional belgian detective hercule poirot in regard to his gray matter: 'this affair must be unravelled from within.' he tapped his forehead. 'these little grey cells. It is up to them as you say over here.' (12 Dec 1998) |
