  1. What type of epithelial tissue is this?

    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
  11. What type of connective tissue is this?

    Areolar tissue

    (from fascia between muscles)
  12. What type of connective tissue is this?

    Adipose tissue

    (from subcutaneous layer)
  13. What type of connective tissue is this?

    Reticular connective tissue

    (from spleen)
  14. What type of connective tissue is this?

    Dense regular connective tissue

    (from tendon)
  15. What type of connective tissue is this?

    Elastic connective tissue

    (from artery wall)
  16. What type of connective tissue is this?

    Hyaline cartilage

    (from coastal cartilage of ribs)
  17. What type of connective tissue is this?

    Elastic cartilage

    (from ear)
  18. What type of connective tissue is this?

    Fibrocartilage

    (from intervetebral discs)
