Senior histology

  1. 1. Janet J. Nelson RN, CMA
  2. 2. ….(with more than 100 types). Similar cells with extracellular matrix and fibers form tissues …..related tissues form organs …..related organs for systems and PRESTO we have a human body
  3. 3. 1. CELLS 2. FIBERS 3. EXTRACELLULAR MATRIX These components vary from tissue to tissue!!
  4. 4. TISSUE #1 EPITHELIAL TISSUE
  5. 5. LABEL SIMPLE EPITHELIAL TISSUE
  6. 6. http://www.cedarville.edu/personal/sullivan/histology/epi
  7. 7. What view is this?
  8. 8. What view is this?
  9. 9. Ciliated lines most of the respiratory tract
  10. 10. Sweat gland ducts are examples of stratified cuboidal epithelium...usually however there are only two layers of cells.
  11. 11. Stratified Columnar epithelium is rare. One place you can find it is in the largest ducts of salivary glands (parotid, submandibular, etc). The basal layer of cells are cuboidal cells and the layer nearest the apical surface includes columnar cells. The large droplets are mucus, in Goblet cells.
  12. 12. When the tissue is stretched, the cells, especially those on the surface, become flat. This allows organs lined with transitional epithelium to change shape without damaging the epithelial lining.
  13. 13. Orange arrow points to free surface . Image on the left is an empty bladder. Image on right a full bladder
  14. 14. EXOCRINE GLANDS EXOCRINE (such as sweat, sebaceous glands)
  15. 15. MEMBRANES SEROUS (visceral and parietal) MUCOUS
  16. 16. MEMBRANES CUTANEOUS PERIOSTEUM SYNOVIAL
  17. 17. Review: http://wps.aw.com/bc_marieb_happlace_7_oa/42/109 64/2807009.cw/index.html http://msjensen.cehd.umn.edu/webanatomy/histolog y/hist_epith_1_m.htm
  18. 18. TISSUE #2 CONNECTIVE TISSUE
  19. 19. CHARACTERISTICS: Blood supply varies Extracellular matrix varies Fibers vary Notice all the different connective tissue of the elbow
  20. 20. http://www.cedarville.edu/personal/sullivan/histolog y/connective/index.htm
  21. 21. Reticular tissue highly magnified
  22. 22. Ligament………………Tendon……………….Aponeuroses
  23. 23. ELASTIC CONNECTIVE TISSUE
  24. 24. View video of Haversian system: http://www.youtube.com/watch?v=u1EdyPqhbpA
  25. 25. Cells…..Fibers…….Extracellular Matrix HYALINE CARTILAGE C.T.
  26. 26. Image from intervertebral disk
  27. 27. ADIPOSE TISSUE C.T.
  28. 28. VASCULAR C.T.
  29. 29. Review: http://wps.aw.com/bc_marieb_happlace_7_oa/42/109 64/2807009.cw/index.html
  30. 30. TISSUE #3 MUSCULAR TISSUE
  31. 31. MUSCULAR TISSUE Skeletal Muscle Cardiac Muscle Smooth (Visceral) Muscle
  32. 32. TISSUE #4 NERVOUS TISSUE
  33. 33. NERVOUS TISSUE NEURONS & NEUROGLIA
  34. 34. REVIEW
