                        (Page numbers in parentheses are for the new book)

  Epithelial Membranes: composed of an epithelial sheet with underlying CT layer (77)
         NOT THE SAME AS EPITHELIAL TISSUE!

                Cutaneous membranes: Epithelial sheet with underlying dense CT layer (77)
                       Skin
                       Dry
                       Keritinized cells

                Mucous membranes: Epithelial sheet with underlying loose CT (77)
                      all body cavities open to the outside
                            o respiratory tract
Picture                     o digestive tract
p (78)                      o urogenital tract

                Serous membranes: Simple squamous epithelium sheet with scant loose CT
                              underlying it. (79)

                           Has two layers
                               o visceral & parietal peritoneum
                               o visceral & parietal pericardium
                               o visceral & parietal pleura


  Epithelium: refers to all epithelial tissues
  Mesothelium: refers to only the epithelial tissue of the serous membranes (not the underlying CT)
  Endothelium: refers to epithelial tissue that lines inside of hollow organs

  Synovial membranes: (p79)
        Composed entirely of CT
        Lines cavities around joints
        Provides smooth surface and secretes lubricating fluid
        Lines bursae and tendon sheaths
        Picture (80) Know parts

  Don’t forget the Review Exercises on (p. 509)
                                             PARTS LIST

                                               For exercises 7
This is just a parts list. This is not all that you need to know for the test, although it is a very large
part of it. Your goal is to be able to identify these parts by name from a picture, model or
microscope slide, and be able tell the location and the function of each part.
