| smooth muscle tissue | <anatomy, pathology, physiology> Muscle tissue in vertebrates made up from long tapering cells that may be anything from 20-500m long. Smooth muscle is generally involuntary and differs from striated muscle in the much higher actin/myosin ratio, the absence of conspicuous sarcomeres and the ability to contract to a much smaller fraction of its resting length. Smooth muscle cells are found particularly in blood vessel walls, surrounding the intestine (particularly the gizzard in birds) and in the uterus. The contractile system and its control resemble those of motile tissue cells (e.g. Fibroblasts, leucocytes) and antibodies against smooth muscle myosin will cross react with myosin from tissue cells, whereas antibodies against skeletal muscle myosin will not.

| nephrogenic tissue | The tissue from which the pronephros, mesonephros, and metanephros develop. (05 Mar 2000) |
| nerve tissue protein s 100 | Highly acidic calcium-binding protein found in large concentration in the brain and believed to be glial in origin; also found in other organs in the body. (12 Dec 1998) |
| 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) |
