| rough microsome | <cell biology> Small vesicles obtained by sonicating cells and that are derived from the rough endoplasmic reticulum. Have bound ribosomes and can be used to study protein syntheis. Origin: Gr. Soma = body (17 Dec 1997) |
|---|---|
| rough strain | <microbiology> Bacterial strains that have altered outer cell wall carbohydrate chains causing colonies on agar to change their appearance from smooth to dull. In Streptococci the smooth strains are virulent whereas the rough strains are not. This is partly because the rough strains are much more readily phagocytosed. (17 Dec 1997) |
| rough trees | Live trees of commercial species which do not contain a sawlog because of roughness, poor form, splits, or cracks. Includes all living trees of noncommercial species. (05 Dec 1998) |
| endoplasmic | Referring to the endoplasm. (05 Mar 2000) |
| reticulum | Origin: L. Dim. Of rete a net. <anatomy> The second stomach of ruminants, in which folds of the mucous membrane form hexagonal cells; also called the honeycomb stomach. The neuroglia. Source: Websters Dictionary (01 Mar 1998) |
| reticulum cell | Cells of the reticuloendothelial system, found particularly in lymph nodes, bone marrow and spleen. In lymph nodes they are stromal cells and probably not reticuloendothelial cells in the current sense of that term. (18 Nov 1997) |
| reticulum cell sarcoma | <tumour> Obsolete term for histiocytic lymphoma. (05 Mar 2000) |
| reticulum trabeculare sclerae | The network of fibres (pectinate ligaments) at the iridocorneal angle between the anterior chamber of the eye and the venous sinus of the sclera; it contains spaces between the fibres that are involved in drainage of the aqueous humor, and is composed of two portions: the corneoscleral part, the part attached to the sclera, and the uveal part, the part attached to the iris. Synonym: reticulum trabeculare sclerae, Gerlach's valvula, Hueck's ligament, ligamentum annulare bulbi, pectinate ligaments of iridocorneal angle, pillar of iris, trabecular meshwork, trabecular network, trabecular zone. (05 Mar 2000) |
| Golgi internal reticulum | <cell biology> Intracellular stack of membrane bounded vesicles in which glycosylation and packaging of secreted proteins takes place. Part of the GERL complex. Synonym: Golgi body, Golgi vesicles, dictyosome (in plants), parabasal body (in flagellate protozoa). (11 Jan 1998) |
| cistern of cytoplasmic reticulum | See: cisterna. (05 Mar 2000) |
| corneoscleral part of trabecular reticulum | The anterior part of the trabecular reticulum, located between the sinus venosus sclerae, the scleral spur, and the posterior limiting membrane of the cornea. Synonym: pars corneoscleralis reticuli trabecularis. (05 Mar 2000) |
| sarcoplasmic reticulum | Endoplasmic reticulum of striated muscle, specialised for the sequestration of calcium ions that are released upon receipt of a signal relayed by the T tubules from the neuromuscular junction. (18 Nov 1997) |
| stellate reticulum | A network of epithelial cells disposed in a fluid-filled compartment in the centre of the enamel organ between the outer and inner enamel epithelium. (05 Mar 2000) |
| Ebner's reticulum | A network of nucleated cells in the seminiferous tubules. (05 Mar 2000) |
