| interpeduncular cistern | A dilation of the subarachnoid space in front of the pons, where the arachnoid membrane stretches across between the two temporal lobes over the base of the diencephalon. See: interpeduncular fossa. Synonym: cisterna interpeduncularis, basal cistern, cisterna basalis, cisterna cruralis, Tarin's space. (05 Mar 2000) |

| lumbar cistern | Enlargement of subarachnoid space between inferior end of spinal cord (vertebral level L-2) and inferior end of subarachnoid space or dura mater (vertebral level S2); occupied by the dorsal and ventral roots of lumbosacral spinal nerves (which constitute the cauda equina), the filum terminal, and cerebrospinal fluid. Site for lumbar puncture and spinal anaesthesia. (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) |
| 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) |
| 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) |
| 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) |
| 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) |
| 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) |
