Tissue is a cellular organizational level intermediate between cells and a complete organism. Hence, a tissue is an ensemble of cells, not necessarily identical, but from the same origin, that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues. The study of tissue is known as histology or, in connection with disease, histopathology. The classical tools for studying tissues are the paraffin block in which tissue is embedded and then sectioned, the histological stain, and the optical microscope. In the last couple of decades, developments in electron microscopy, immunofluorescence, and the use of frozen tissue sections have enhanced the detail that can be observed in tissues. With these tools, the classical appearances of tissues can be examined in health and disease, enabling considerable refinement of clinical diagnosis and prognosis. From Wikipedia under the

From Google News Search: "Biological tissue" From a biological perspective, how does a tattoo work? Q. They are permanent and yet with the thousands of times epithelial tissue regenerates, it never takes the whole tattoo away, why is this? Asked by Teenie Theenie - Thu May 14 10:23:38 2009 - - 4 Answers - 0 Comments A. I'm a nurse, and I'm also a tattoo artist. From a biological perspective, a tattoo works because the needle in the tattoo gun pushes the ink about 1/16 of an inch below the level of the epidermis (the outer layer of skin), placing the ink between the dermis (inner layere of skin) and subcutaneous layer (the layer between the dermis and fat). The reason that the ink stays as long as it does, is because of the level where the ink is. Epithelial tissue, which is mainly the epidermis dying and regenerating itself, has little effect on the ink, as long as the artist knows what they're doing. If the artist doesn't go deep enough, the tattoo fades quickly, if they go too deep, it causes inflamation, and a raised effect of the skin that has been… [cont.] Answered by Duane Walker - Thu May 14 11:05:18 2009 What are the possible damages of alpha and beta particles? Q. the damages to biological tissues? Asked by muzikchik - Mon Sep 22 13:34:14 2008 - - 1 Answers - 0 Comments A. Ionizing radiation damages mRNA, DNA, and proteins directly and by generation of highly reactive free radicals. Large doses of ionizing radiation cause cell death, whereas lower doses interfere with cell proliferation. Damage to other cellular components can result in progressive hypoplasia, atrophy, and eventually fibrosis. Genetic damage may result in malignant transformation or a transmissible genetic defec For details, see: Answered by bdwolfhound - Mon Sep 22 13:40:21 2008 Which level of biological organization is found in all organisms?
