| rough-surfaced endoplasmic reticulum | Endoplasmic reticulum in which ribosomal granules are applied to the cytoplasmic surface of the cisternae; involved in the synthesis and secretion of protein via membrane-bound vesicles to the extracellular space. Synonym: chromidial substance, ergastoplasm, rough-surfaced endoplasmic reticulum. (05 Mar 2000) |
|---|
| agranular endoplasmic reticulum | Endoplasmic reticulum that is lacking in ribosomal granules; involved in synthesis of complex lipids and fatty acids, detoxification of drugs, carbohydrate synthesis, and sequestering of Ca++. Synonym: smooth-surfaced endoplasmic reticulum. (05 Mar 2000) |

| granular endoplasmic reticulum | Endoplasmic reticulum in which ribosomal granules are applied to the cytoplasmic surface of the cisternae; involved in the synthesis and secretion of protein via membrane-bound vesicles to the extracellular space. Synonym: chromidial substance, ergastoplasm, rough-surfaced endoplasmic reticulum. (05 Mar 2000) |
| rough endoplasmic reticulum | <cell biology> Membrane organelle of eukaryotes that forms sheets and tubules. Contains the receptor for the signal receptor particle and binds ribosomes engaged in translating mRNA for secreted proteins and the majority of transmembrane proteins. Also a site of membrane lipid synthesis. The membrane is very similar to the nuclear outer membrane. The lumen contains a number of proteins that possess the C terminal signal KDEL. (17 Dec 1997) |
| smooth endoplasmic reticulum | <cell biology> An internal membrane structure of the eukaryotic cell. Biochemically similar to the rough endoplasmic reticulum, but lacks the ribosome binding function. Tends to be tubular rather than sheet like, may be separate from the rough endoplasmic reticulum or may be an extension of it. Abundant in cells concerned with lipid metabolism and proliferates in hepatocytes when animals are challenged with lipophilic drugs. Acronym: SER (18 Nov 1997) |
| smooth-surfaced endoplasmic reticulum | Endoplasmic reticulum that is lacking in ribosomal granules; involved in synthesis of complex lipids and fatty acids, detoxification of drugs, carbohydrate synthesis, and sequestering of Ca++. Synonym: smooth-surfaced endoplasmic reticulum. (05 Mar 2000) |
| transitional endoplasmic reticulum | <cell biology> Region at the boundary of the rough endoplasmic reticulum and the Golgi. Transport vesicles are responsible for the transfer of secretory proteins from this part of the rough endoplasmic reticulum to the Golgi system. (18 Nov 1997) |
| endoplasmic reticulum | <cell biology> Membrane system that ramifies through the cytoplasm. The membranes of the endoplasmic reticulum are separated by 50-200 nm and the cisternal space thus enclosed constitutes a separate compartment. The Golgi region is composed of flattened sacs of membrane that together with endoplasmic reticulum and lysosomes constitute the GERL system. See: smooth endoplasmic reticulum, rough endoplasmic reticulum. (18 Nov 1997) |
| endoplasmic reticulum, rough | A type of endoplasmic reticulum (er) where polyribosomes are present on the cytoplasmic surfaces of the er membranes. This form of er is prominent in cells specialised for protein secretion and its principal function is to segregate proteins destined for export or intracellular utilization. (12 Dec 1998) |
| endoplasmic reticulum, smooth | A type of endoplasmic reticulum lacking associated ribosomes on the membrane surface. It exhibits a wide range of specialised metabolic functions including supplying enzymes for steroid synthesis, detoxification, and glycogen breakdown. In muscle cells, smooth endoplasmic reticulum is called sarcoplasmic reticulum. (12 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) |
