      - mineral storage
      - assistance in movement
      - blood cell formation

        place of attachment for ligaments and tendons
        
        perforating fibers
        
        "sharpies - fish hooks"
        
        tendons connect to periosteum which then connects to compact bone with perforating fibers
      - medullary cavity (marrow cavity)
        
        filled with yellow marrow
        
        lined with endosteum
      - diaphysis (shaft)
      - epiphyseal line
      - epiphyses
      - articular cartilage
  - - - in spongy bone
      - gelatinous and soft in texture
      - function
        
        blood cell formation
    - - not actually yellow
      - adipose
      - function
        
        nutrient storage
  - - - primarily in endosteum
      - multinucleate
        
        very large
        
        has microvilli
        
        secrete enzymes that breakdown bone
        
        it can move around
        
        its also a phagocyte
    - - location
        
        periosteum
        
        endosteum
      - osteoblast
  - - - 35% organic
      - 65% inorganic
    - - short bones
      - flat bones
      - irregular bones
      - long bone
- - - - very short interconnecting fibers
        
        examples

        gumphosis
        
        location
        
        where the tooth meets the alveolus (tooth socket)
        
        periodental ligaments
        
        connectors made of DICT
