| EGL | external granule layer |
|---|---|
| GCL | granule cell layer |
| MCG | mast cell granule |
| SGC | small granule-containing |
| cortical granule | <cell biology, gynaecology> Specialised secretory vesicles lying just below the plasma membrane of the egg, that fuse and release their contents immediately after fertilization (activation) to prevent polyspermy. (13 Nov 1997) |
|---|---|
| presecretory granule | Vesicles near the maturation face of the Golgi. Synonym: Golgi condensing vacuoles. (18 Nov 1997) |
| proacrosomal granule | <cell biology> Small carbohydrate-rich granule's appearing in vesicles of the Golgi apparatus of spermatids. They coalesce into a single acrosomal granule contained within an acrosomal vesicle. (05 Mar 2000) |
| prozymogen granule | <cell biology> Stage in the development of a mature secretory vesicle (zymogen granule). (18 Nov 1997) |
| secretory granule | A membrane-bound particle, usually protein, formed in the granular endoplasmic reticulum and the Golgi complex. (05 Mar 2000) |
| seminal granule | One of the minute granular bodies present in the semen. (05 Mar 2000) |
| specific granule | One of the two main classes of granules found in neutrophils: contain lactoferrin, lysozyme, Vitamin B12 binding protein and elastase. Are released more readily than the azurophil (primary) granules which have typical lysosmal contents. (18 Nov 1997) |
| storage granule | 1. <cell biology> Membrane bounded vesicles containing condensed secretory materials (often in an inactive, zymogen, form). Otherwise known as zymogen granules or condensing vacuoles. 2. Granules found in plastids or in cytoplasm, assumed to be food reserves, often of glycogen or other carbohydrate polymer. (18 Nov 1997) |
| neutrophil granule | A granule stainable with the neutral component of stains, e.g., the Romanovsky-type blood stains. (05 Mar 2000) |
| Nissl granule | <cell biology> Discrete clumps of material seen by phase contrast microscopy in the perikaryon of some neurons, particularly motor neurons. They are basophilic and contain much RNA, are actually regions very rich in rough endoplasmic reticulum. Their reaction following damage to neurons is characteristic, they disperse through the cytoplasm giving a general basophilia to the whole cell body. (18 Nov 1997) |
| delta granule | A granule of a delta cell. (05 Mar 2000) |
| iodophil granule | A granule that stains brown with iodine; found in many of the polymorphonuclear leukocytes in pneumonia, erysipelas, scarlet fever, and various other acute diseases. (05 Mar 2000) |
| oxyphil granule | A granule that stains with an acid dye such as eosin. Synonym: oxyphil granule. (05 Mar 2000) |
| elementary granule | A particle of blood dust, or haemoconia. (05 Mar 2000) |
| eosinophil granule | A granule that stains with eosin. (05 Mar 2000) |
