Support Tissues (Ordinary Connective Tissues (Loose CT (Adipose - Padding,…

- - - - White adipose storage
        
        Blood capillaries
        
        Insulation as poor conductor
      - Brown adipose tissue
        
        Thermoregulation in young
        
        Blood capillaries
        
        Nuclei central, not squeezed to periphery
        
        Many small lipid droplets
    - - Blood vessels
    - - Tea strainer (lymph)
      - Reticulin protein (stained by silver impregnation)
  - - - Surround organs (forms organ capsule)
      - Interwoven fibres = added strength
    - - Tendons, ligaments
      - Broad, flat regular layers of collagen
    - - Protein = elastin
      - Anywhere in body needing to strech with recoil
        
        e.g. Aorta, lungs
- - - - Most common
      - Secrete ground substance
        
        Fewer collagen fibres, more gel (GAG) so smooth glossy appearance
      - Rigidity but without full weight of bone
        
        Bronchi, septum of nose, ends of bones (where dont want friction)
    - - High proportion of collagen fibres
      - High tensile strength
        
        Intervertebral discs and attachment sites of some tendons to bone
    - - Higher content of elastic fibres (elastin)
      - Flexibilty
        
        Pinna (outer part of ear)
        
        Deform tissue, but return it to original state
    - - Perichondrium is layer on all cartilage tissues
        
        Chondrocytes originate here
      - Appositional (secrete at edges) growth or interstitial (chondroblasts secrete more on inside) growth
      - Avascular
      - Lacunae (lake the cells sit in)
- - - - Collagen fibres
        
        alpha chains -> collagen molecules (triple helices) -> collagen fibrils --> collagen fibres
      - GAG (glycosaminoglycans)
        
        Hydrated sugars
        
        Form proteoglycans with small protein core
