    • stratified
  7. pseudostratified columnar epithelium
    • includes several cell types with varying shapes and functions 
    • *nuclei at different heights*

  9. What accounts for the majority of the volume in a cell?
    matrix
  10. Connective Tissue Functions
    • binding and supporting (cartilage) 
    • protecting (cartilage and bone)
    • insulating (adipose tissue)
    • storing energy reserve (adipose/ bone marrow)
    • transportation (blood)
    • establishing structural framework (cartilage and bone)
  11. 3 General Categories of Connective Tissue
    • 1. Connective Tissue Proper
    • 2. Fluid Connective Tissue
    • 3. Supporting Connective Tissue
  12. function of connective tissue proper
    build and maintain
  13. fibroblasts
    produce protein fibers
  14. fibrocytes
    • matured fibroblasts
    • maintain protein fibers
  15. adipocytes
    storage cells
  16. mesencheymal
    stem cells
  17. temporary immune cells in connective tissue proper
    • macrophages 
    • mast cells 
    • lymphocytes 
    • microphages 
    • melanocytes
  18. 3 Types of Fibers in Connective Tissue Proper
    • 1. Collagen
    • 2. Reticular 
    • 3. Elastic
  19. Collagen Fiber
    • long, straight, unbranched 
    • most common
    • inflexible 
    • fibrous protein wound like rope
  20. reticular protein
    • branching interwoven network of fibers 
    • stroma
  21. elastic
    • elastic protein
    • branched and wavy
    • bounce back from distortion
  22. types of loose connective tissue proper
    • areolar 
    • adipose 
    • reticular
  23. areolar
    • least specialized
    • loosely organized
    • viscous ground substance 
    • elastic fibers 
    • return to original shape if distorted 
    • viscosity of molasses
  24. Where are reticular fibers found?
    liver, kidney, spleen, lymph nodes, and bone marrow
  25. types of dense connective tissue proper
    • regular 
    • elastic
    • irregular
  26. irregular
    • thicker collagen fibers arranged irregularly 
    • run in more than 1 plane
    • stresses in many directions
  27. regular
    • densely packed collagen fibers 
    • run parallel
    • resist tension in one direction
    • few cells other than fibroblasts  
    • poorly vascularized 
    • tendons, ligaments, aponeuroses
  28. adipose tissue
    • high concentration of lipid 
    • adipocytes make up majority of mass
    • metabolically active
  29. brown fat
    • adipose tissue with lots of adipocytes with lots of mitochondria 
    • found in infants to help keep them warm because they can't shiver yet
  30. 2 types of fluid connective tissues
    • blood 
    • lymph
  31. 3 subdivisions of extracellular fluid
    • 1. plasma
    • 2. interstitial fluid
    • 3. lymph
  32. 2 types of supporting connective tissues
    • 1. cartilage 
    • 2. bone
  33. 3 major types of cartilage
    • 1. hyaline
    • 2. elastic
    • 3. fibrocartilage
  34. hyaline
    • face, nose, ribs
    • most common
    • matrix appears glassy, blue-white
    • stiff but flexible support
  35. elastic
    • hyaline but with many more elastic fibers 
    • tolerates distortion without damage
  36. fibrocartilage
    • resists compression
    • prevents bone to bone contact
    • limits movement
  37. osteons
    hard matrix
  38. osteocytes
    • well supplied by blood vessels 
    • canaliculi- channels for communication
  39. 3 types of muscle tissues
    • 1. skeletal
    • 2. cardiac 
    • 3. smooth
  40. How do the 3 types of muscle organization differ?
    in protein fiber organization
  41. skeletal muscle
    • long cells 
    • muscle fibers 
    • incapable of dividing
    • produced by myosatellite cells
    • striated appearance
  42. cardiac muscle
    • only in heart 
    • caridocytes
    • 1-5 nuceli 
    • intercalated discs- junctions between cardiocytes
    • smaller and shorter than skeletal
  43. smooth muscle
    • small cells with single nucleus 
    • can divide (the only type)
    • different organization of fibers 
    • around hollow organs and in walls of blood vessels 
    • tapered at the end
  44. nervous tissue
    • specialized for conduction of electrical impulses 
    • 98% is concentrated in brain and spinal cord
