| cavernous tissue | A tissue with numerous vascular spaces that may become engorged with blood. Synonym: cavernous tissue. (05 Mar 2000) |
|---|---|
| reticular tissue | Retiform tissue, a tissue in which the argyrophilic collagenous fibres form a network and that usually has a network of reticular cells associated with the fibres. (05 Mar 2000) |
| periapical tissue | Tissue surrounding the apex of a tooth, including the apical portion of the periodontal membrane and alveolar bone. (12 Dec 1998) |
| granulation tissue | Highly vascularised tissue that replaces the initial fibrin clot in a wound. Vascularisation is by ingrowth of capillary endothelium from the surrounding vasculature. The tissue is also rich in fibroblasts (that will eventually produce the fibrous tissue) and leucocytes. (18 Nov 1997) |
| mesenchymal tissue | Embryonic connective tissue. See: mesenchyme. (05 Mar 2000) |
| peripheral lymphoid tissue | Secondary lymphoid tissue, not necessarily located peripherally. See: lymphoid tissue. (18 Nov 1997) |
| mesonephric tissue | Intermediate mesoderm situated in the thoracic and lumbar regions of the embryo or foetus; it evolves into the mesonephros and associated structures. (05 Mar 2000) |
| metanephrogenic tissue | Tissue derived from the intermediate mesoderm caudal to mesonephric levels and concerned with the formation of the nephrons of the metanephros. (05 Mar 2000) |
| ground tissue | <plant biology> Plant tissues other than those of the vascular system and the dermal tissues. Composed of relatively undifferentiated cells. (18 Nov 1997) |
| guided tissue regeneration | The repopulating of the periodontium, after treatment for periodontal disease. Repopulation is achieved by guiding the periodontal ligament progenitor cells to reproduce in the desired location by blocking contact of epithelial and gingival connective tissues with the root during healing. This blocking is accomplished by using synthetic membranes or collagen membranes. (12 Dec 1998) |
| chondroid tissue | In an adult, tissue resembling cartilage. In an embryo, an early stage in cartilage formation. Synonym: fibrohyaline tissue, pseudocartilage. (05 Mar 2000) |
| gut-associated lymphoid tissue | <physiology> Peripheral lymphoid organ consisting of lymphoid tissue associated with the gut (Peyer's patches, tonsils, mesenteric lymph nodes and the appendix). It is especially rich in B-cells and is responsible for localised immunity to pathogens such as bacteria, viruses, and parasites. (20 Sep 2002) |
| chromaffin tissue | Tissue in medulla of adrenal gland containing two populations of cells, one producing adrenaline, the other noradrenaline. The catecholamine is associated with carrier proteins (chromogranins) in membrane vesicles (chromaffin granules). (18 Nov 1997) |
| rubber tissue | A thin sheet of rubber used as a cover in surgical dressings. (05 Mar 2000) |
| Mohs' fresh tissue chemosurgery technique | Chemosurgery in which superficial cancers are excised after fixation in vivo. (05 Mar 2000) |
