| bone tissue | A connective tissue, the matrix of which consists of collagen fibres and ground substance and in which are deposited calcium salts (phosphate, carbonate, and some fluoride) in the form of an apatite. Synonym: bone tissue. (05 Mar 2000) |

| border tissue movements | The action of the muscles and other tissues adjacent to the borders of a denture. (05 Mar 2000) |
| brain tissue transplantation | Transference of brain tissue, either from a foetus or from a born individual, between individuals of the same species or between individuals of different species. (12 Dec 1998) |
| brown adipose tissue | A thermogenic type of adipose tissue containing a dark pigment, and arising during embryonic life in certain specific areas in many mammals, including man. It is prominent in the newborn of all species in which it occurs and remains a distinct and conspicuous tissue in the adults of certain species, especially those that hibernate. It is also called brown adipose tissue. (12 Dec 1998) |
| cancellous tissue | Latticelike or spongy osseous tissue. (05 Mar 2000) |
| cardiac muscle tissue | See: cardiac muscle. (05 Mar 2000) |
| Gamgee tissue | A thick layer of absorbent cotton between two layers of absorbent gauze, used in surgical dressings. (05 Mar 2000) |
| gelatinous tissue | A type of connective tissue little differentiated beyond the mesenchymal stage; its ground substance of glycoproteins is abundant and contains fine collagenous fibres and fibroblasts; in its most characteristic form, it appears in the umbilical cord as Wharton's jelly. Synonym: gelatinous tissue. (05 Mar 2000) |
| Verhoeff's elastic tissue stain | <technique> A stain for tissue sections in which a mixture of haematoxylin, ferric chloride, and Lugol's iodine solution is used; tissue may be counterstained, if desired, with eosin or van Gieson's stain; elastic fibres and nuclei appear blue-black to black while collagen and other components are shades of pink to red. (05 Mar 2000) |
| cartilaginous tissue | See: cartilage. (05 Mar 2000) |
| 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) |
| 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) |
