  1. What type of epithelial tissue is this?

    Image Upload 1
    Stratified squamous epithelium

    (nonkeratinized) (from esophagus)
  2. What are the nine (9) types of Epithelial tissues?
    • 1. Simple squamous epithelium - single layer, flattened cells
    • 2. Simple cubodial epithelium - single layer, cube-shaped cells
    • 3. Simple columnar epithelium - single layer, elongated cells
    • 4. Pseudostratified columnar epithelium - single layer, elongated cells
    • 5. Stratified squamous epithelium - many layers, top cells flattened
    • 6. Stratified cubodial epithelium - 2 to 3 layers, cube-shaped cells
    • 7. Stratified columnar epithelium - top layer of elongated cells, lower layers of cube-shaped cells
    • 8. Transitional epithelium - many layers of cube-shaped and elongated cells9. Glandular epithelium - unicellular or multicellular
  3. Epithelium Tissue:

    Describe Simple Squamous Epithelium.
    • - single layer of flattened cells
    • - nuclei is usually broad and thin
    • - substances pass easily through
    • - line air sacs
    • - forms walls of capillaries
    • - line blood vessels
    • - line lymphatic vessels
  4. Epithelium Tissue:

    Describe Simple Cuboidal Epithelium.
    • - single layer of cube-shaped cells
    • - centerally located spherical nuclei
    • - lining kidney tubules
    • - covers (surface) the overies
    • - lines ducts of some glands (salivary, pancreas, liver)
  5. Epithelium Tissue:

    Describe Simple Columnar Epithelium.
    • - single layer of elongated cells
    • - nuclei usually near the basement membrane
    • - sometimes possess microvilli
    • - often have goblet cells (flask-shaped grandular cells) = secrete a mucus (can see a little, maybe)
    • - can be ciliated or noncilated
    • - lines the uterus, stomach, intestines, portions of the digestive track
  6. Epithelium Tissue:

    Describe Pseudostratified Columnar Epithelium.
    • - single layer of elongated cells (appear stratified)
    • - nuclei at two or more levels
    • - appear striated- often have cilia
    • - often have goblet cells
    • - lines the respiratory passageways (trachea and bronchi)
  7. Epithelium Tissue:

    Describe Stratified Squamous Epithelium.
    • - many cell layers
    • - top cells are flat
    • - younger cells in the deeper layers (cell division occuring) are cuboidal or columnar
    • - older cells nearest the free surface a flatened (pushed out there)
    • - can accumulat keratin (dead, dead, dead) = as the older cells are pushed outward
    • - outer layer of skin
    • - line oral cavity, vagina, and anal canal
  8. Epithelium Tissue:

    Describe Stratified Cubodial Epithelium.

    (wasn't one on the lab report)
    • - 2 to 3 layers
    • - cube-shaped cells*
    • - line ducts of mammary glands, sweat glands, salivary glands, and pancreas, (and only the
    • developing portino of reproductive system)
  9. Epithelium Tissue:

    Describe Stratified Columnar Epithelium.

    (wasn't one on the lab report)
    • - top layer of elongated cells
    • - lower layers of cube-shaped cells
    • - line part of male urethea and part of pharynx
  10. Epithelium Tissue:

    Describe Transitional Epithelium.
    • - many cell layers elongated and cube-shaped irregular cells
    • - (remember: microscope) the long underlying conective tissue is distincitive
    • - lines the inner lining of the urinary bladder
    • - lines the ureters, and part of urethra
    • - form barrier, prevents content from going back into the system
