     is the bone shaft or body - the long' cylindrical, main portion of the bone . 
  2. Definision of epiphysis?
    growing over ; singular the distal and proximal ends of the bone. 
  3. Definision of metaphyses?
    between; the regions in a mature bone where the diaphysis joins the ephiphysis. 
  4. Definition of articular cartilage?
    is a thin layer of hyaline cartilage coving the part of the ephiphysis where the bone forms a joint or articulation. 
  5. Definition of periosteum?
     is a tough sheath of dense irregular Connective tissue that surrounds the bone surface wherever it is not covered by articular cartilage . 
  6. Definition of medullary cavity?
    (marrow) is the space within the diaphysis that contains fatty yelloe bone marrow in adults.
  7. Definition of a endosteum?
