  1. Cutaneous Membrane:
    List the Tissue Types: membrane composition (epithelial/connective),
    Common locations,
    General functions.
    epithelial...connective tissue...found in the skin functions are: secretion, oil and sweat, waterproofing, keratin, bacteriostatic acid mantle and sebum, and protect against chemical and mechanical damage keratinization and continuity.
  2. Mucous:

    List the Tissue Types:
    membrane composition (epithelial/connective), Common locations,
    General functions.
    • membrane composition epithelial, connective tissue...(location) lining of the digestive, respiratory and urogenital tracts
    • general functions are secretion mucus, absorption, ciliated for movement of substances.
  3. Serous:
    List the Tissue Types:
    membrane composition (epithelial/connective), Common locations,
    General functions.
    • epithelial, connective tissue; 
    • lining of closed ventral body cavities; 
    • secretion serous fluid; decreases friction.
  4. Synovial:
    List the Tissue Types:
    membrane composition (epithelial/connective), Common locations,
    General functions.
    • connective tissue; 
    • lining of the joint cavities of freely moveable joints; 
    • secretion synovial fluid; decreases friction.
  5. Membrane type in joints, bursae and tendon sheaths
  6. Epithelium of this membrane is always simple squamous epithelium
  7. The only membrane type in which goblet cells are found
  8. The dry membrane with keratinizing epithelium
  9. "wet" membranes
  10. Adapted for absorption and secretion
  11. Has parietal and visceral layers
  12. Knowing that -itis is the suffix meaning "inflammation of" what do peritonitis, pleurisy and pericarditis patological conditions have in common?
    all are inflammations of serous membrane
  13. Why are these conditions accompanied by great deal of pain?
    when serous membranes become inflamed, insufficient serous fluid may be produced. As a result, friction increases and adhesions may form.
  14. epithelial membrane
    simple organ consisting of an epithelial sheet bound to an underlying layer of connective tissue proper.
  15. cutaneous membrane
    is the skin, a dry membrane with a keratinizing epithelium (the epidermis).
  16. mucous membrane
    are composed of epithelial cells resting on a layer of loose connective tissue called the lamina propia.
  17. goblet cells
    columnar epithelial cells with a large mucus containing vacuole (goblet) in their apical cytoplasm.
  18. serous membrane
    are also epithelial membranes. Also lines the interior of blood vessels (endothelium) and the heart (endocardium).
  19. parietal layer
    lines a body cavity
  20. viceral layer
    covers the outside of the organs in that cavity.
  21. synovial membranes
    composed of connective tissue; they contain no epithelial cells. Line the cavities containing the joints, providing a smooth surface and secreting a lubricating fluid.
  22. Explain: cutaneous membrane and mucous membrane

    1. Cutaneous membrane – skin, a dry membrane (organ system) consisting of keratinized epithelium (epidermis).

    2. Mucous membrane – line body cavities that are open to the exterior (respiratory,(mucosae) digestive & urogenital tracts).

    • – wet or moist membranes bathed by secretions of lubricating mucus;
    • except urinary mucosa, urine.
  23. Explain serous membrane
    Image Upload

    • Serous membrane (serosae)– line body cavities that are closed to the exterior (except dorsal
    • body cavity and female peritoneal cavity). 

    – line interior of blood vessels (endothelium) & heart (endocardium).

    • – entire wall of capillaries is composed of serosa, which allows a selectively
    • permeable membrane between blood & tissue fluid of the body.
    • –  double layer, consist of a parietal layer (outer wall) & visceral layer (inner wall).

    –  each layer secretes a thin lubricating fluid (serous fluid) that lubricates organs & body walls, which reduces friction against other organs & against body cavity walls.

    • – pleura; encloses lungs
    • – pericardium; surrounds the heart
    • – peritoneum; associates w/the walls of the abdominopelvic cavity and line most organs w/in the cavity
  24. list the two major categories of membranes
    Epithelial and synovial membranes.
  25. Explain synovial membranes
  26. Synovial Membranes – are composed entirely of connective tissue & contain no epithelial cells.
    • – line the cavities surrounding the joints by providing a smooth surface & secreting a lubricating fluid that reduces friction.
    • – line smaller sacs of connective tissue (bursae & tendon sheaths) that cushion structures moving against each other during muscle activity.
