CA1 LP 1&2: Connective Tissue

  1. Characteristics of Connective tissue: (10)
    • 1. Binds structures
    • 2. Provides support
    • 3. Protects
    • 4. Fills spaces
    • 5. Stores fat
    • 6. Produces blood cells
    • 7. Repairs damaged tissue
    • 8. Not tightly packed; substance b/t called matrix
    • 9. Cells can divide
    • 10. Has various vascularity (blood supply)
  2. Major cell types of Con Tissue: (8)
    • 1. Fibroblast
    • 2. Macrophage
    • 3. Mast
  3. Fibroblast cells produce the following fibers: (3)
    • 1. Collagen
    • 2. Elastin
    • 3. Reticular
  4. The following are characteristics of Collagen fibers: (6)
    • 1. Maintains shape (like silly putty)
    • 2. Made up of thick threads of protein
    • 3. Flexible
    • 4. Slightly elastic
    • 5. Great strength
    • 6. Holds structures together
  5. The following are characteristics of Elastin fibers: (4)
    • 1. Makes up: vocal chords, resp sys air passages
    • 2. Made of thinner elastic strands
    • 3. VERY elastic
    • 4. Weaker than collagen
  6. The following are characteristics of Reticular fibers: (3)
    • 1. Makes up the spleen
    • 2. Made of VERY thin collagen fibers
    • 3. Supporting network of tissues
  7. The following are characteristics of Macrophage cells: (5)
    • 1. Begin as white blood cells
    • 2. Can move
    • 3. Specialize in phagocytosis (eating)
    • 4. Important in protection against infection
    • 5. "Garbage men"
  8. The following are characteristics of Mast cells: (4)
    • 1. Aid in injury healing
    • 2. Large cells located near blood vessels
    • 3. Release heparin > Prevents blood clotting
    • 4. Release histamine > Promotes inflammation **
  9. The types of Con Tissue are: (6)
    • 1. Loose
    • 2. Adipose
    • 3. Reticular
    • 4. Dense
    • 5. Elastic
    • 6. Cartilage
  10. Loose Con Tissue is: (2)
    • 1. Compose primarily of fibroblasts
    • 2. Make up fascia
  11. Adipose tissue is: (3)
    • 1. Fat
    • 2. Specialized cells that store fat
    • 3. Continue to enlarge to store more fat
  12. Reticular tissue is: (2)
    • 1. Made up of thin collagen fibers
    • 2. Support orgas
    • > Spleen
    • > Liver
  13. Dense Con Tissue: (3)
    • 1. Holds parts together
    • 2. Tendons
    • 3. Ligaments
  14. Elastic Con Tissue is: (2)
    • 1. Elastic fibers
    • 2. Found in large arteries/ligaments of spial column
  15. Cartilage is: (4)
    • 1. Rigid connective tissue
    • 2. Composed primarily of collagen fibers
    • 3. Have chondrocytes
    • > Live in small houses (lacunae)
    • > Lack direct blood supply**
    • > Divide slowly**
    • ** Heals slowly bc of this
    • 4. Covered by perichondrium > contains blood supply for cart cells
  16. Types of cartilage: (3)
    • 1. Hyaline
    • 2. Elastic
    • 3. Fibrocartilage
  17. Hyaline (aka Articular Cart) is: (4)
    • 1. Most abundant
    • 2. Like hard white plastic
    • 3. Covers ends of bones
    • 4. Very smooth; reduces friction
  18. Elastic cartilage is: (3)
    • 1. Flexible
    • 2. Contains many elastin fibers
    • 3. External ears
  19. Fibrocartilage is: (4)
    • 1. Toughest of 3 types
    • 2. Shock absorber
    • 3. Intervertebral discs
    • 4. Menisci of knee
  20. Bones are: (3)
    • 1. Most rigid of CT
    • 2. Matrix contains calcium and phosphate
    • 3. Osteocytes
    • > lay layers of bone matrix around them (lamellae)
    • > Live in houses (lacunae)
    • > Form circles around central (haversian) canals > contain blood vessels
  21. Blood is: (4)
    • 1. Produced by cells inside bone (bone marrow)
    • 2. Red blood cells
    • > Carry oxygen and carbon dioxide
    • 3. White blood cells
    • > Fight infection
    • 4. Platelets
    • > Help form clots
