| substantia reticularis | A filamentous plasmatic material, beaded with granules, demonstrable by means of vital staining in the immature red blood cells. Synonym: alpha substance, filar mass, filar substance, substantia reticularis, substantia reticulofilamentosa. Synonym: reticular formation. (05 Mar 2000) |

| 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) |
