To identify the bone shapes and name examples of bones representative of shapes. 4. To identify the major regions and structures of a long bone. 5. To explain the role of the inorganic salts and organic matrix in providing flexibility and hardness to bone. 6. To locate and identify the three major types of cartilages. NOTES: I.
