| nervous tissue | A highly differentiated tissue composed of nerve cells, nerve fibres, dendrites, and a supporting tissue (neuroglia). (05 Mar 2000) |
|---|---|
| subcutaneous tissue | The soft tissue immediately underlying the skin or epidermis. (27 Sep 1997) |
| nodal tissue | See: atrioventricular node, sinuatrial node. (05 Mar 2000) |
| dartoic tissue | Tissue resembling tunica dartos. (05 Mar 2000) |
| dermal tissue | <botany> Outer covering of plants, that includes the epidermis and periderm nonliving bark). See: dermis. (18 Nov 1997) |
| indifferent tissue | Undifferentiated, nonspecialised, embryonic tissue. (05 Mar 2000) |
| interstitial tissue | <pathology> Rather general term for mesodermally derived tissue that may be more or less specialised. Cartilage and bone are specialised connective tissue, as is blood, but the term is probably better reserved for the less specialised tissue that is rich in extracellular matrix (collagen, proteoglycan etc.) and that surrounds other more highly ordered tissues and organs. (18 Nov 1997) |
| islet tissue | <anatomy> Groups of cells found within the pancreas: A cells and B-cells secrete insulin and glucagon. See: D cells. (18 Nov 1997) |
| osseous 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) |
| osteogenic tissue | A connective tissue with the property of forming osseous tissue. (05 Mar 2000) |
| osteoid tissue | Osseous tissue prior to calcification. (05 Mar 2000) |
| tissue | A group of similar cells united to perform a specific function. (16 Dec 1997) |
| tissue adhesives | Substances used to cause adherence of tissue to tissue or tissue to non-tissue surfaces, as for prostheses. (12 Dec 1998) |
| tissue banks | Centres for acquiring, characterizing, and storing organs or tissue for future use. (12 Dec 1998) |
| tissue basophil | <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) |
