Chapter 5-Histology
Show Answers:

  1. A group of similiar cells (& matrix) that work together to perform a specific structural or physiological role in an organ
  2. Structure that is composed of two or more tissue types
  3. Fibrous proteins and sugars; a clear gel (gound substance, tissue fluid, extracellular fluid-ECF, intestional fluid, or tissue gel
  4. Stratified squamous epithelium (epidermis) over connective tissue (dermis)
    Cutaneous Membrane
  5. Lines passageways open to teh external enviroment
    Mucous membrane (mucosa)
  6. Internal membrane (simple squamous epithelium over areorar connective tissues, covers organs and lines walls of bady cavities, secretes serous fluid
    Serous membrane
  7. Lines joint cavities (connective tissue layer only; scretes synovial fluid)
    Synovial membrane
  8. Lines passages that open to the external enviromen (digestive, respiratory, urinary, and reproductive tracts

    Consist of two to three layers:
    Areolar Connective Tissues
    Smooth muscle layer

    absorptive, secretory, and protective functions; covered with mucus
    Mucous Membrane (Mucosa)
  9. Consist of one or more layers of closely adhering cells; only a small amount of intercellular material; no blood vessels, forms the covering and lining of organs and body cavities
    Epithelial Tissue
  10. Layer between epithelium and underlying connective tissue; anchors the two together; contains collagen, laminin, fabronectin, heparing sulfate

    Cannot really see
    Basement Membrane
  11. Single row of thin cells, permits rapid diffusion or transport; secretes serous fluid

    Ex: alveoli, glomeruli, endothelium, serous
    Simple Squamous Epithelium
  12. Single layer of square or round cells; absorption adn secretion, mucus production and movement

    Ex: Liver, thyroid, mammary, salivary glands, bronchioles, and kidney tubules
    Simple Cuboidal Epithelium
  13. Single row tall, narrow cells, oval nuclei in basal half of cells, border microvilla, can be cilated and possess goblet cells

    Absorption adn secretion; mucus secretion (ex lining of GI track, uterus, kindey, and uterine tubes
    Simple Columnar Epithelium
  14. Wineglass-shaped mucus secreting gland cells found in simple columnar and pseudostratified epithelia
    Goblet Cells
  15. Looks multilayered; all touch basesment membrane; nuclei at several layers, has cilia and goblet cells; secretes adn propels mucus (ex: respiratory tract and male uretha)
    Pseudostratified Epithelium
  16. Mulitiple cell layers with cells becoming flat and scaley toward surface; resist abrasion; retards water loss through skin; resist penetration by pathogenic organisms

    (Ex: epidermis; palms and soles heavily kerantinzed)
    Kerantinized Stratified Squamous
  17. Same as kerantinzed epithelium without the surface layer of dead cells; resist abrasion and penetration of pathogens (Ex: Tongue, oral mucosa, esophagus and vagina)
    Nonkerantinized Stratified Squamous
  18. Difference between nonkerantized adn kerantize...
    basically protection
