2. Epithelial Tissue Location –Covers body surface = epidermis –Lines hollow organs, cavities, ducts, tubes (like blood vessels) –Forms glands (sweat, salivary, oil)

3. Epithelial Tissue Characteristics –Very little intercellular (extracellular) substance between cells –No blood vessels –Free surface contacts air or fluid (this means that the cell’s free surface does not contact another cell at this surface, but instead contacts air/fluid)

4. Epithelial Tissue –Basement membrane connects epithelium to underlying connective tissue –Cells very readily divide, because epithelium is subject to abrasion

6. Epithelial Tissue Classification according to shape of cell at the free surface: –Cuboidal –Squamous (thin, flat) –Columnar

8. Epithelial Tissue Classification according to number of cell layers: –Stratified (2 or more layers) –Simple (one layer)

9. Epithelial Tissue Specific names of tissues –Simple Squamous Epithelium

10. Epithelial Tissue –Simple Columnar Epithelium

11. Epithelial Tissue –Simple Cuboidal Epithelium

12. Epithelial Tissue –Stratified Squamous Epithelium

13. Epithelial Tissue –Pseudostratified Ciliated Columnar Epithelium

14. Epithelial Tissue –Transitional Epithelium
