Transcript of "heather tissues project"

  1. 1. Tissues <ul><li>picture </li></ul><ul><li>Group of cells in structure and function </li></ul><ul><li>Four types of tissues </li></ul><ul><li>Nervous , connective , epithelial </li></ul>
  2. 2. Epithelial Tissues <ul><li>picture </li></ul><ul><li>Composed almost entirely of cells </li></ul><ul><li>Widespread throughout the body </li></ul><ul><li>Lines body cavities and hollow organs, and major tissues in gland </li></ul><ul><li>different numbers of layers </li></ul><ul><li>Simple epithelial , stratified epithelial </li></ul>
  3. 3. Simple Epithelial <ul><li>pict </li></ul><ul><li>One cell layer thick </li></ul><ul><li>subdivided according to the shape and function of its cells. </li></ul><ul><li>Simple Squamous , simple cubodial , simple columnar </li></ul>
  4. 4. Simple Squamous <ul><li>Thin & flat </li></ul><ul><li>Functions in diffusion & filtration </li></ul><ul><li>Provides a slick friction </li></ul><ul><li>Simple Cubodial , Simple columnar </li></ul>
  5. 5. Simple Cubodial <ul><li>Single layer of cube-like cells with large spherical central nuclei </li></ul><ul><li>Functions in secretion & absorption </li></ul><ul><li>Simple Columnar, Simple squamous </li></ul>
  6. 6. Simple Columnar <ul><li>Single layers of tall cells with oral nuclei; many contain nuclei </li></ul><ul><li>Celia helps move substances through passageway </li></ul><ul><li>Lines digestive tract & gallbladder </li></ul><ul><li>Simple Cubodial, Simple Squamous </li></ul>
  7. 7. Pseudostratified columnar <ul><li>Single layer of cells with different heights </li></ul><ul><li>Present in male sperms </li></ul><ul><li>The nuclei is at different layers with in the tissues </li></ul><ul><li>Simple Squamous , Simple Cubodial , simple columnar </li></ul>
  8. 8. Stratified Epithelial <ul><li>pict </li></ul><ul><li>Consists of multiple layers of cells </li></ul><ul><li>Classified into shape </li></ul><ul><li>Many cells in thickness </li></ul><ul><li>Squamous, cubodial, columnar, transitional </li></ul>
  9. 9. Stratified squamous <ul><li>Thick membrane, of several layers of cells </li></ul><ul><li>Forms external layer of skin epidermis </li></ul><ul><li>cubodial, columnar, transitional </li></ul>
  10. 10. Stratified Cubodial <ul><li>Two cell layers thick </li></ul><ul><li>Found in the sweat glands </li></ul><ul><li>Squamous, columnar, transitional, </li></ul>
  11. 11. Stratified Columnar <ul><li>Found in the pharynx, male urethra </li></ul><ul><li>Occurs at transitional areas </li></ul><ul><li>Squamous, cubodial, transitional </li></ul>
  12. 12. Transitional Stratified <ul><li>consists of multiple layers of epithelial cells which can contract and expand. </li></ul>Squamous, columnar, cubodial
  13. 13. Connective Tissue <ul><li>Found throughout the body </li></ul><ul><li>Binds, protects, insulates, transports </li></ul><ul><li>Bone, blood, connective tissue proper, cartilage </li></ul>
  14. 14. Bone <ul><li>Hard & help support, protect & provide levers </li></ul><ul><li>Has a calcified matrix with collagen fibers </li></ul><ul><li>Stores calcium, minerals and fats </li></ul>
  15. 15. Blood <ul><li>Found with in blood vessels </li></ul><ul><li>White blood cells in the matrix (plasma) </li></ul>
  16. 16. Proper Connective <ul><li>consists of cells and extracellular matrix </li></ul><ul><li>Two main groups; dense & loose </li></ul><ul><li>Loose, dense </li></ul>
  17. 17. Connective Tissue Proper: Loose <ul><li>There are three types </li></ul>Areolar, reticular, adipose
  18. 18. Areolar <ul><li>3 connective tissue fibers </li></ul><ul><li>Wraps & cushions organs </li></ul><ul><li>Distributed throughout the body </li></ul><ul><li>reticular, adipose </li></ul>
  19. 19. Reticular <ul><li>Cells lie in a fiber network </li></ul><ul><li>Forms a soft internal skeleton; that supports cell types </li></ul><ul><li>Found in lymph nodes, bone marrow & the spleen </li></ul><ul><li>Areolar, Adipose </li></ul>

  22. 22. Dense regular <ul><li>Parallel collagen fibers w/ some elastic fibers </li></ul><ul><li>Attaches, muscle to bone; muscle to muscle; bone to bone </li></ul><ul><li>Found in tendons, ligaments & aponeuroses </li></ul>
  23. 23. Dense irregular <ul><li>Irregularly arranged collagen fibers with some elastic fibers </li></ul><ul><li>Major cell type is fibroblasts </li></ul><ul><li>Structural strength </li></ul>regular
  24. 24. Cartilage <ul><li>Is a Type of dense & connective tissues </li></ul><ul><li>Avascular (contains no blood vessels) </li></ul><ul><li>Fibrocartilage, elastic, hyaline </li></ul>
