Epithilum and connective tissues
Show Answers:

  1. Where can Simple Squamous Epithelium be found?
    Alveoli (air sacs of lungs), lining of heart chambers and endothelium (lumen of blood vessels), Mesothelium (serious membrane of body cavities)
  2. Where can Simple Cuboidal Epithelium be found?
    Thyroid gland follicles, kidney tubules, ducts of secretory glands. Regions of most glands, surface of ovaries.
  3. Where can Nonciliated Simple Columnar Epithelium be found?
    Lining of the digestive tract, lining of the stomach does not contain goblet cells
  4. Where can Ciliated Simple Columnar Epithelium be found?
    Lining of the uterine tubes and larger bronchioles of respiratory tract
  5. Where can Transitional Epithiliam be found?
    Urinary bladder lining
  6. Where can Pseudostratified Columnar Epithelium be found?
    • Ciliated form lines most of the respiratory tract, nasal cavity, part of pharynx, larynx. Trachea and bronchi
    • non ciliated is rare but can be found in the lining of the epididymis
  7. Where can Nonkeratinized Stratified Squamous Epithelium be found?
    Lining the oral cavity, part if the pharynx, esophagus, vagina and anus.
  8. Where can Keratinized Stratified Squamous Epithelium be found?
    Epidermis of the skin
  9. Where can Stratified Columnar Epithelium be found?
    Male Urethra
  10. Where can Stratified Cuboidal Epithelium be found?
    • duct of sweat gland
    • Mammary glands
    • salivary glands
    • Most exocrine glands
  11. Three types of junctions
    • 1. Tight Junctions
    • 2. Desmosomes
    • 3. Gap Junctions
  12. Naming Cell Shape
    • 1. Squamous: Flattened, looks like fried egg
    • 2. Cubodial: Cells are as tall as wide, often have round nuclei
    • 3.Columnar: Tall and elongated
  13. Naming Cell Layers
    • 1.) simple- single layer of cells, does not offer good protection, concerned with absorption, secretion and filtration
    • 2.) Stratified- More than one layer
    • 3.) Pseudostratified- Pseudo means false, appears to be stratified but upon closer look all cells are attached to basement membrane
  14. How to recognize epithelium tissue
    • There is a free surface
    • Cells are smashed right next to each other
    • There is a basement membrane
