| Golgi type I neuron | <physiology> Nerve cells whose long axons leave the gray matter of which they form a part. (05 Mar 2000) |
|---|---|
| Golgi zone | <cell biology> Part of the cytoplasm occupied by the Golgi apparatus, in secretory cells of exocrine glands, a zone between the nucleus and the luminal surface. (05 Mar 2000) |
| Holmgren-Golgi canals | <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) |
| trans Golgi network | <cell biology> A complex of membranous tubules and vesicles, near the trans face of the Golgi, which is thought to be a major intersection for intracellular traffic of vesicles. (18 Nov 1997) |
| trans-Golgi reticulum | That part of the Golgi apparatus that takes newly processed proteins and delivers them to secretory vesicles that will fuse with other biomembranes (e.g., the plasma membrane). (05 Mar 2000) |
| amniotic corpuscle | One of a number of small ovoid or rounded, sometimes laminated, bodies resembling a grain of starch and found in nervous tissue, in the prostate, and in pulmonary alveoli; of little pathological significance, and apparently derived from degenerated cells or proteinaceous secretions. Synonym: amniotic corpuscle, amylaceous corpuscle, amyloid corpuscle, colloid corpuscle. (05 Mar 2000) |
| amyloid corpuscle | One of a number of small ovoid or rounded, sometimes laminated, bodies resembling a grain of starch and found in nervous tissue, in the prostate, and in pulmonary alveoli; of little pathological significance, and apparently derived from degenerated cells or proteinaceous secretions. Synonym: amniotic corpuscle, amylaceous corpuscle, amyloid corpuscle, colloid corpuscle. (05 Mar 2000) |
| axis corpuscle | Axile corpuscle, the central portion of a tactile corpuscle. (05 Mar 2000) |
| basal corpuscle | <cell biology> Structure found at the base of eukaryotic cilia and flagella consisting of a continuation of the nine outer sets of axonemal microtubules but with the addition of a C tubule to form a triplet (like the centriole). May be self replicating and serves as a nucleating centre for axonemal assembly. Anchored in the cytoplasm by rootlets. Synonymous with kinetosome. (18 Nov 1997) |
| Bizzozero's corpuscle | <haematology> A discoid cell (3m diameter) found in large numbers in blood, important for blood coagulation and for haemostasis by repairing breaches (small breaks) in the walls of blood vessels. Platelet _ granules contain lysosomal enzymes, dense granules contain ADP (a potent platelet aggregating factor) and serotonin (a vasoactive amine). They also release platelet-derived growth factor which presumably contributes to later repair processes by stimulating fibroblast proliferation. Synonym: thrombocytes. (09 Oct 1997) |
| blood corpuscle | <haematology> There are three main types of cell in the blood stream. The red cell, which carries oxygen, the white cell, which fights infections and the platelet, which helps prevent bleeding. The correct balance between each cell type must be maintained for the body to remain healthy. (13 Nov 1997) |
| bone corpuscle | <pathology> Osteoblast that is embedded in bony tissue and which is relatively inactive. (18 Nov 1997) |
| bridge corpuscle | <cell biology> Specialised cell junction characteristic of epithelia into which intermediate filaments (tonofilaments of cytokeratin) are inserted. The gap between plasma membranes is of the order of 25-30nm and the intercellular space has a medial band of electron dense material. Desmosomes are particularly conspicuous in tissues such as skin that have to withstand mechanical stress. Origin: Gr. Soma = body (18 Nov 1997) |
| ghost corpuscle | A hypochromic, crescent-shaped erythrocyte, probably resulting from artifactual rupture of a red cell with loss of haemoglobin. Synonym: achromacyte, achromatocyte, ghost corpuscle, phantom corpuscle, Ponfick's shadow, shadow corpuscle, shadow, Traube's corpuscle. Origin: G. A-priv. + chroma, colour, + kytos, hollow (cell) (05 Mar 2000) |
| red corpuscle | A red blood cell. (18 Nov 1997) |
