| Palade granule | <cell biology> A small particulate organelle found in prokaryotes and eukaryotes and also within mitochondria and chloroplasts, but differing in size and composition. Made of two subunits, each being an RNA protein complex. Ribosomes are responsible for the translation of mRNA which may occur in the cytoplasm (see polyribosomes) or on rough endoplasmic reticulum. Origin: Gr. Soma = body (18 Nov 1997) |

| volutin granule | Metachromatic granules containing polyphosphate, a linear phosphate polymer found in bacteria, fungi, algae and some higher eukaryotes that may serve as a stock of phosphate. (18 Nov 1997) |
| glycogen granule | Glycogen occurring in cells as beta granule's which average about 300 A |
| membrane-coating 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) |
| granule | <pharmacology> A small quantity of a solid substance, smaller than a grain. Origin: L. Granulum (18 Nov 1997) |
| granule cell | Type of neuron found in the cerebellum. (18 Nov 1997) |
| granule cell of connective tissue | <cell biology, immunology> Resident cell of connective tissue that contains many granules rich in histamine and heparan sulphate. Release of histamine from mast cells is responsible for the immediate reddening of the skin in a weal and flare response. Very similar to basophils and possibly derived from the same stem cells. Two types of mast cells are now recognised, those from connective tissue and a distinct set of mucosal mast cells, the activities of the latter are T-cell dependent. (05 Jan 1998) |
| granule cells | Small nerve cell bodies in the external and internal granular layers of the cerebral cortex, small nerve cell bodies in the granular layer of the cerebellar cortex. (05 Mar 2000) |
| rod granule | The nucleus of a retinal cell connecting with one of the rods. (05 Mar 2000) |
| chromatic granule | Any readily stainable granule, a granule of chromophil (Nissl) substance. Synonym: chromatic granule. (05 Mar 2000) |
| chromophil granule | Any readily stainable granule, a granule of chromophil (Nissl) substance. Synonym: chromatic granule. (05 Mar 2000) |
| compound granule cell | A lipid-laden microglial phagocyte commonly seen at the edge of healing brain infarcts, a result of cellular phagocytosis of lipid from necrotic or degenerating brain cells. Synonym: compound granule cell. Origin: Ger. Gitterzelle, fr. Gitter, lattice, wire-net (05 Mar 2000) |
| cone granule | Nucleus of a retinal cell connecting with one of the cones. (05 Mar 2000) |
| polar granule | <biology> Granules containing a basic protein found in insect eggs that induce the formation of and become incorporated into germ cells. (18 Nov 1997) |
| 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) |
