| 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) |
| kappa granule | <cell biology> Primary lysosomal granules found in neutrophil granulocytes, contain a wide range of hydrolytic enzymes. Sometimes referred to as primary granules to distinguish them from the specific or secondary granules. (02 Jan 1998) |
| keratohyalin granule | Granules found in living cells of keratinising epithelia and which contribute to the keratin content of the dead cornified cells. Some, but not all, contain sulphur rich keratin. (18 Nov 1997) |
| Zimmermann's granule | <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) |
| zymogen granule | <cell biology> Secretory vesicle containing an inactive precursor (zymogen). The contents are often very condensed. (18 Nov 1997) |
| lamellar granule | A membrane-bound granule, 100 to 500 nm in diameter, located in the upper layers of the stratum spinosum of certain stratified squamous epithelia. Synonym: lamellar granule, membrane-coating granule, Odland body. (05 Mar 2000) |
| Langerhans' granule | A small tennis racket-shaped membrane-bound granule with characteristic cross-striated internal ultrastructure; first reported in Langerhans' cells of the epidermis. Synonym: Birbeck's granule. (05 Mar 2000) |
