| 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) |
| fuchsinophil granule | A granule that has an affinity for fuchsin. Synonym: Altmann's granule. (05 Mar 2000) |
| accessory organs of the eye | The eyelids, with lashes and eyebrows, lacrimal apparatus, conjunctival sac, and extrinsic muscles of the eyeball. Synonym: organa oculi accessoria, accessory organs, accessory visual apparatus, adnexa oculi, appendages of eye. (05 Mar 2000) |
| accommodation of eye | The increase in thickness and convexity of the eye's lens in order to focus the image of an external object upon the retina. (05 Mar 2000) |
| amaurotic cat's eye | A yellow reflex from the pupil in cases of retinoblastoma or pseudoglioma. (05 Mar 2000) |
| anterior chamber of eye | The space between the cornea anteriorly and the iris/pupil posteriorly, filled with a watery fluid (aqueous humor) and communicating through the pupil with the posterior chamber. Synonym: camera anterior bulbi, camera oculi anterior, camera oculi major. (05 Mar 2000) |
