Presentation Transcript

  1. Simple Epithelium • Simple squamous • Single layer of flat cells • Usually forms membranes • Lines body cavities • Lines lungs and capillaries

  2. Simple squamous epithelium

  3. Connective tissue Smooth Muscle Blood cells Simple squamous lining of artery (blood vessel)

  4. Simple Epithelium • Simple cuboidal • Single layer of cube-like cells • Common in glands and their ducts • Forms walls of kidney tubules • Covers the ovaries

  5. Simple cuboidal cells

  6. Simple Epithelium • Simple columnar • Single layer of tall cells • Often includes goblet cells, which produce mucus • Lines digestive tract

  7. Simple columnar epithelium

  8. Simple Epithelium • Pseudostratified • Single layer, but some cells are shorter than others • Often looks like a double cell layer • Sometimes ciliated, such as in the respiratory tract • May function in absorption or secretion

  9. Trachea lining Cilia Ciliated pseudostratified columnar epithelium

  10. Stratified Epithelium • Stratified squamous • Cells at the free edge are flattened • Found as a protective covering where friction is common • Locations • Skin • Mouth • Esophagus

  11. Stratified squamous epithelium of epidermis of skin. This is the un-keratinized kind.

  12. Stratified squamous epithelium of epidermis of skin. This is the dried out or keratinized kind.

  13. Stratified Epithelium • Transitional epithelium • Shape of cells depends upon the amount of stretching • Lines organs of the urinary system

  14. Adipose Smooth muscle Transitional epithelium Transitional epithelium Lining of ureter

  15. Transitional epithelium Lining of ureter
