| taste corpuscle | One of a number of flask-shaped cell nests located in the epithelium of vallate, fungiform, and foliate papillae of the tongue and also in the soft palate, epiglottis, and posterior wall of the pharynx; it consists of sustentacular, gustatory, and basal cells between which the intragemmal sensory nerve fibres terminate. Synonym: caliculus gustatorius, gustatory bud, Schwalbe's corpuscle, taste bulb, taste corpuscle. (05 Mar 2000) |

| third 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) |
| thymic corpuscle | Small spherical bodies of keratinised and usually squamous epithelial cells arranged in a concentric pattern around clusters of degenerating lymphocytes, eosinophils, and macrophages; found in the medulla of the lobules of the thymus. Synonym: Hassall's bodies, Hassall's concentric corpuscle, Virchow-Hassall bodies. (05 Mar 2000) |
| touch corpuscle | One of numerous oval bodies found in the papillae of the skin, especially those of the fingers and toes; they consist of a connective tissue capsule in which the axon fibrils terminate around and between a pile of wedge-shaped epithelioid cells. Synonym: corpusculum tactus, Meissner's corpuscle, oval corpuscle, touch corpuscle. (05 Mar 2000) |
| Traube's 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) |
| exudation corpuscle | A cell present in an exudate that assists in the organization of new tissue. Synonym: exudation cell, inflammatory corpuscle, plastic corpuscle. (05 Mar 2000) |
| Zimmermann'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) |
| lymph corpuscle | Lymphatic corpusclelymphoid corpuscle, a mononuclear type of leukocyte formed in lymph nodes and other lymphoid tissue, and also in the blood. (05 Mar 2000) |
