Science Jeff Lee

  1. 1. <ul><li>Created by cells with similar shapes and functions </li></ul><ul><li>Creates “the Fabric” the Body </li></ul><ul><li>Composed of Epithelial, Muscle, Nervous, Connective </li></ul>Epithelial Connective Muscle Nervous Credits
  2. 2. <ul><li>Almost entirely composed of cells </li></ul><ul><li>Can be divided into Simple and Stratified Epithelium </li></ul><ul><li>Classified by the number of cell layers and the cell shape </li></ul>Home Simple Epithelium Stratified Epithelium
  3. 3. <ul><li>Consists of single-celled layers </li></ul><ul><li>Main functions consist of absorption and filtration </li></ul><ul><li>Has three primary shapes </li></ul>Home Simple Squamous Simple Cuboidal Simple Columnar Psuedostratified Columnar Courtesy of akay
  4. 4. <ul><li>Contain a sparse cytoplasm </li></ul><ul><li>They consist of single flattened cells </li></ul><ul><li>Specialize in diffusion and filtration </li></ul><ul><li>Divided into two sections </li></ul>Home Simple Cuboidal Simple Columnar Psuedostratified Columnar Mesothelium Endothelium Courtesy of pbchua
  5. 5. <ul><li>Consists of a cube-like shape </li></ul><ul><li>Contain one large spherical central nuclei </li></ul><ul><li>Primary functions include secretion and absorption </li></ul>Home Simple Squamous Simple Columnar Psuedostratified Columnar
  6. 6. <ul><li>Creates a slick, friction reducing lining </li></ul><ul><li>Found in hollow organs of cardiovascular system </li></ul><ul><li>Allows the exchanges between blood streams and tissue cells </li></ul>Home Mesothelium Courtesy of Partlynch
  7. 7. <ul><li>Found in the serous membrane </li></ul><ul><li>Lines the ventral cavity </li></ul><ul><li>Covers organs </li></ul>Home Endothelium
  8. 8. <ul><li>Contains closely packed cells </li></ul><ul><li>Located in areas of the digestive tract </li></ul><ul><li>Associated mostly with absorption and secretion </li></ul>Home Simple Squamous Simple Cuboidal Psuedostratified Columnar Courtesy of Christi’s Photos
  9. 9. <ul><li>Looks as if many cell layers are present </li></ul><ul><li>May or may not contain cilia and goblet cells </li></ul><ul><li>Location depends on characteristics </li></ul>Home Simple Squamous Simple Cuboidal Simple Columnar Courtesy of Ra5my
  10. 10. <ul><li>Have two more cell layers </li></ul><ul><li>Main concerns include protection </li></ul><ul><li>Identified by apical layer </li></ul>Home Stratified Squamous Stratified Cuboidal Stratified Columnar Transitional
  11. 11. <ul><li>Most commonly found of all stratified epithelia </li></ul><ul><li>Main functions include protection </li></ul><ul><li>May or may not contain keratin </li></ul>Home Stratified Cuboidal Stratified Columnar Transitional
  12. 12. <ul><li>It is rare to find in the body </li></ul><ul><li>Found in the ducts of larger glands </li></ul><ul><li>Consists of only two layers </li></ul>Home Stratified Squamous Stratified Columnar Transitional
  13. 13. <ul><li>Not commonly found in the body </li></ul><ul><li>It is located in smalls amounts in specific areas of the body </li></ul><ul><li>Usually found in junctions of two other types of epithelium </li></ul>Home Stratified Squamous Stratified Cuboidal Transitional
  14. 14. <ul><li>They have the ability to alter their shape </li></ul><ul><li>Basal cells are cuboidal or columnar </li></ul><ul><li>Apical layer consists of domelike or squamous shaped cells </li></ul>Home Stratified Squamous Stratified Cuboidal Stratified Columnar
  15. 15. <ul><li>They are highly cellular </li></ul><ul><li>Responsible for much of </li></ul><ul><li>body’s movement </li></ul><ul><li>Three different types </li></ul>Home Skeletal Muscle Cardiac Muscle Smooth Muscle
  16. 16. <ul><li>Attach to bones of the skeleton </li></ul><ul><li>Forms the body’s flesh </li></ul><ul><li>Allows the body to voluntarily create movement </li></ul>Home Cardiac Muscle Smooth Muscle
  17. 17. <ul><li>Found only in the walls of the heart </li></ul><ul><li>Creates intercalated discs </li></ul><ul><li>Aids in propelling blood throughout the entire body </li></ul>Home Skeletal Muscle Smooth Muscle
