  9. 9. Simple Columnar Epithelial Tissue <ul><li>Single layer of tall cells </li></ul><ul><li>Round to oval nuclei </li></ul><ul><li>Some cells bear cilia </li></ul><ul><li>May contain mucus </li></ul>Simple squamous Epithelial Simple cuboidal Psuedostratified
  10. 10. Simple Cuboidal Epithelial Tissue <ul><li>Consists of a single layer of cells </li></ul><ul><li>Tall wide </li></ul><ul><li>Spherical central nuclei </li></ul>Simple squamous Simple columnar Epithelial Psuedostratified
  11. 11. Pseudostratified Columnar Epithelial <ul><li>Single layer of cells </li></ul><ul><li>Different heights </li></ul><ul><li>Some do not reach free surface </li></ul>Simple squamous Simple columnar Simple cuboidal Epithelial
  12. 12. Stratified Epithelial Tissue <ul><li>Contain 2 or more layers </li></ul><ul><li>More durable than simple epithelial tissues </li></ul><ul><li>Major role is protection </li></ul>Stratified Squamous Stratified Columnar Stratified Cuboidal Transitional
  13. 13. Stratified Squamous Epithelial Tissue <ul><li>Most widespread of the epithelial tissues </li></ul><ul><li>Composed of many thick layers </li></ul><ul><li>Protects the body </li></ul>Epithelial Stratified Columnar Stratified Cuboidal Transitional
  14. 14. Stratified Cuboidal Epithelial Tissue <ul><li>Rare in the body </li></ul><ul><li>Found in the ducts of some of the larger glands </li></ul><ul><li>Have 2 layers of cuboidal cells </li></ul>Stratified Squamous Stratified Columnar Epithelial Transitional
  15. 15. Transitional Epithelial Tissue <ul><li>Resembles stratified squamous </li></ul><ul><li>It has basal cells </li></ul><ul><li>Dome shaped or squamous depending </li></ul>Stratified Squamous Stratified Columnar Stratified Cuboidal Epithelial
