1. Cartilage is an avascular tissue with no nerve supply.

FALSE
TRUE
--------------------------------------------------------------------------------

2. Cartilage, made up of 60 - 80 % water, is well designed to resist compression and functions to cushion joint surfaces.

TRUE
FALSE

--------------------------------------------------------------------------------

3. Chondrocytes receive oxygen and nutrients via diffusion through the extracellular matrix.

FALSE
TRUE

--------------------------------------------------------------------------------

4. Cartilage forming cells, chondrocytes, rapidly divide throughout an individual's life and thus cartilage tissue heals easily after an injury.

TRUE
FALSE

--------------------------------------------------------------------------------

5. All bones of the skull are formed by intramembraneous ossification.

TRUE
FALSE

--------------------------------------------------------------------------------

6. Bone marrow is found in all bones.

FALSE
TRUE

--------------------------------------------------------------------------------

7. Osteons are located only in spongy bone.

TRUE
FALSE

--------------------------------------------------------------------------------

8. New bone is produced at both the periosteum, the membrane that surrounds the outer surface of the bone, and the endosteum, the membrane that lines the central canals of osteons and surrounds the trabeculae in spongy bone.

TRUE
FALSE

--------------------------------------------------------------------------------

9. All bones have a distinct marrow cavity.

FALSE
TRUE

--------------------------------------------------------------------------------

10. Perforating canals run through the center of the osteon, carrying blood vessels and nerves to the bone cells.

FALSE
TRUE

--------------------------------------------------------------------------------

11. Bone tissue is well designed to resist compression and tension. The collagen fibers found in bone function to resist compression and the mineral salts resist tension and bending forces.

TRUE
FALSE

--------------------------------------------------------------------------------

12. Bone is an avascular organ with little nerve supply.

FALSE
TRUE

--------------------------------------------------------------------------------

13. Blood cells are formed in yellow bone marrow, within the diaphysis of the bone.

TRUE
FALSE

--------------------------------------------------------------------------------

14. A number of factors influence bone deposition including mechanical stress on the bone as a result of exercise.

TRUE
FALSE
--------------------------------------------------------------------------------

15. Osteomalacia is applied to disorders in adults in which the bones are inadequately mineralized. This condition can be treated by hormone replacement therapy.

FALSE
TRUE
