- - - - Immovable
    - - Little movement
  - - - Articular cartilage
      - Articular cavity
      - Articular capsule
      - Synovial fluid
      - Reinforcing ligaments
      - Nerves and vessels
      - Articular disc

        Cube-shaped, compact+spongy
      - Flat
        
        Flat-shaped, compact+spongy
      - Long
        
        Diaphysis (shaft)
        
        Medullary cavity
        
        Epiphysis (ends)
        
        Articular cartilage+epiphyseal line
      - Irregular
      - MICROSCOPIC STRUCTURE:
        
        Compact Bone:dense outer layer
        
        Location: every bone is covered with it.
        
        Spongy Bone:trabeculae with open spaces filled with red or yellow bone marrow. RED BONE MARROW-soft tissue; location: axial bones and proximal epiphyses of femur + humerus. YELLOW BONE MARROW-adipose; location: medullary cavity of long bones
        
        Location: ends of long bone, flat bones (between compact bone)
      - FOUR TYPES OF BONE CELLS:
        
        Osteoblast
        
        Function:create extracellular matrix
        
        Location:periosteum and endosteum
        
        Osteocyte
        
        Function:maintain healthy bone tissue
        
        Location:(in lacuna)compact + spongy bones
        
        Osteogenic(stem)
        
        Function:create osteoblasts and stem cells
        
        Location:periosteum and endosteum
        
        Osteoclast
        
        Function:fusion of several leukocytes;phagocyte (breaks down bone)
        
        Location:endosteum
    - - Elastic
        
        Function: toleration of repeated bending
      - Fibrocartilage
        
        Function: strong compression and strong tension forces
      - Hyaline
        
        Function: support through flexibility and resilience
