  1. epithelial tissue
    • cover body surface
    • lines body cavities and ducts
    • forms glands
  2. connective tissue
    • protects and supports the body and organs
    • binds organs together
    • stores energy reserves
  3. Muscular tissue
    • movement 
    • body temp
  4. nervous tissue
    • interprets nerve impulse
    • nerve impulse coordinate body activities
  5. cell shape - squamous
    flat, scale like, - attach to make mosiac pattern
  6. cuboidal
    • cube shape
    • appear as hexagons
  7. columnar
    tall and cylindrical/ rectangular shape ( digestive)
  8. Transitional
    • combination of shapes- squamous, cuboidal, columnar
    • ( distention, expansion)
  9. membrane: mucous
    lines bodies cavities that are open to the exterior 

    function: protection and secretion
  10. membrane: serous
    • lines body cavities to the interior, 
    • function: secretion and protection
  11. membrane:cutaneous
    skin and outside of body for insulation/ protection
  12. membrane: synovial
    • second layer of articular capsule of synovial joint 
    • function: secretion
  13. mesenchyme
    • forms all other connective tissues
    • embryonic tissue
    • loose or altogether ( speckled)
  14. con: areolar
    • loose woven fibers
    • membrane around blood vessels,nerves, body organs
    • function: strength, elasticity, support
  15. con: adipose
    • loose connective fibers
    • kidney, heart behind eyes
    • function: insulation, and fat storage
  16. con: elastic
    • squamos cells, where elasticity necessary
    • Function: strength
  17. Con: elastic cartilage
    • located in epiglottis, external ear ( squiggly lines thread like elastic fibers)
    • fuction; stretch passage of objects
  18. con: dense regular
    interwoven fibrous bundles, tendons ligaments ( connects bone to muscle or bone)
  19. Con: fibrocartilage
    • The symphysis pubis intervertebral disk
    • Function: strength and rigidity
  20. con: Dense irregular
    • Matrix of shine white fibroblast bone sucle tendons 
    • function: provides strong connection between structure
  21. con: hyaline
    • avascular, ribs nose, trachea 
    • Function: absorbs shock reduces friction
  22. simple squamous:
    • single layer flat
    • lines heart, blood vessels lymphatic system
  23. simple cuboidal:
    • squares, close fitted polygons 
    • secretion, absorption
  24. simple columnar:
    • rectangular, nuclei at base of cell
    • protects underlying tissue secretion, absorption
  25. stratified squamous:
    • flat superficial layers, surface layers lost, 
    • protection
  26. stratified cuboidal:
    • multilayer of cube cells,
    • protection and little secretion and absorption
  27. stratified columnar:
    • multilayer rectangular
    • protection/ secretion
  28. pseudostratified:
    all cells touch basement membrane not all reach surface, contain goblet, reproduction ducts,
  29. transitional:
    • flat superficial layers 
    • outer cells stretch, allows expansion, hold shape
  30. gland:
    specialized cells that secrete substances into ducts or blood
  31. endocrine gland:
    ductless secrete their product into the blood ( hormones)
  32. exocrine gland:
    secrete product into ducts at skin surface or organ
  33. hyaline cartilage:
    • most abundant
    • absorbs shock
    • reduces friction
    • forms embryonic skeleton
  34. basal cell carcinoma:
    skin cancer, seldom metastasizes
