Document Summary
Chapter 3: tissue: a tissue is a group of cells that usually have a common origin in an embryo and function together to carry out specialized activities. The structure and properties of tissue are in uenced by factors such as the nature of the extracellular material that surrounds the tissue cells and the connections between the cells that compose the tissue. Types of tissue: body tissues can be classi ed into four basic types according to their structure and function, epithelial tissue covers body surfaces, and lines hollow organs, body cavities, and ducts; it also forms glands. Clinical connection: biopsy: a biopsy is the removal of a sample of living tissue for microscopic examination. This procedure is used to help diagnose many disorders, and to discover the cause of unexplained infections and in ammations. Both normal and potentially diseased tissues are removed for purposes of comparison. Cell junctions: cell junctions are contact points between the plasma membranes of tissue cells.
