| nucleus reticularis thalami | A sheet of fairly large neurons covering the lateral, ventral, and rostral surfaces of the thalamus; its reticular appearance is caused by the numerous fascicles of the thalamic peduncles which traverse the nucleus The nucleus receives numerous fibres from the cerebral cortex but it has no cortical projection. Synonym: nucleus reticularis thalami. (05 Mar 2000) |

| dermatopathia pigmentosa reticularis | A persistent purplish network-patterned discoloration of the skin caused by dilation of capillaries and venules due to stasis or changes in underlying blood vessels including hyalinization; rarely appears as a developmental defect. Synonym: angiitis livedo reticularis, dermatopathia pigmentosa reticularis, livedo racemosa. (05 Mar 2000) |
| zona reticularis | The inner zone of the adrenal cortex. This zone consists of an anastomosing network of cells which resemble those of the zona fasciculata except for the fact that they contain less lipid. The mitochondria are elongated and contain a mixture of tubular and flattened cristae. (12 Dec 1998) |
| foetal reticularis | Synonym: foetal adrenal cortex. Synonym: androgenic zone. Synonym: X zone. (05 Mar 2000) |
| formatio reticularis | <anatomy, neurology> A region extending from the pons & medulla oblongata through the mesencephalon, characterised by a diversity of neurons of various sizes and shapes, arranged in different aggregations and enmeshed in a complicated fibre network. (12 Dec 1998) |
| livedo reticularis | A persistent purplish network-patterned discoloration of the skin caused by dilation of capillaries and venules due to stasis or changes in underlying blood vessels including hyalinization; rarely appears as a developmental defect. Synonym: angiitis livedo reticularis, dermatopathia pigmentosa reticularis, livedo racemosa. (05 Mar 2000) |
| livedo reticularis idiopathica | An extensive and permanent form of livedo reticularis; in rare instances associated with central arterial disease. (05 Mar 2000) |
| livedo reticularis symptomatica | A discoloration or mottling of the skin due to some demonstrable cause, such as seen in erythema ab igne, and in certain tuberculids. See: cutis marmorata. (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 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) |
| substantia compacta | The compact, noncancellous portion of bone that consists largely of concentric lamellar osteons and interstitial lamellae. Synonym: substantia compacta, compact substance, substantia compacta ossium. (05 Mar 2000) |
| substantia compacta ossium | The compact, noncancellous portion of bone that consists largely of concentric lamellar osteons and interstitial lamellae. Synonym: substantia compacta, compact substance, substantia compacta ossium. (05 Mar 2000) |
| substantia corticalis | The superficial thin layer of compact bone. Synonym: substantia corticalis, cortical substance. (05 Mar 2000) |
