The bone and cartillage - Coggle Diagram

- - - - Extremities on both sides, articular cartilage
      - Covered by hyaline cartilage
      - Little knobby parts
    - - Below epiphysis. conical part of bone
      - Triangle part
    - - Middle part of bone
    - - Inside of bone
      - Replaces medullary cavity at extremities
      - Contains trabeculae and spaces containing bone marrow and BV
    - - Dense outer surface of bone
      - aka compact bone
    - - Between epiphysis and metaphysis
      - Important in growth of young animals
    - - Formed by cancellous bone, cortical bone not found everywhere or else it is too heavy
      - In radiographs, the growth plate is shown dark because it is hyaline cartilage
    - - Outer layer made of CT
      - Thicker
    - - Inner layer made of CT
      - Thinner
    - - Contains bone marrow
        
        Red in young animal, older animals it is yellow
        
        Forms RBC
  - - - Inside the Osteon is the haversian canal which has BV and nerves, the volkmann canal connects the two osteons
    - - In medllary cavity and interstial spaces of spongey bone
      - Red= young, yellow= adult
  - - - Largest source of blood, middle diaphysis
      - Runs through nutrient foramen
    - - Important for quick regeneration
    - - Enters at extremities, does not enter through articular surface
    - - Enters through metaphysis
    - - Arteries
        
        Anastomoses
        
        Between nutrient and metaphyseal arteries
        
        Good collateral circulation
        
        Two hollow structures connect with each other
      - Veins
        
        Thin walled and accompany arteries
        
        Cortical capillaries drain into venules within periosteum
      - NO LYMPHATIC VESSELS
      - NERVES ACCOMPANY LARGER VESSELS
