15 Points Per Correct Answer - No time limit  



1. The "axial skeleton" consists of which of the following sections of the body?
    Neck, trunk and limbs
    Head, neck and trunk
    Limbs only
    Neck and trunk


2. Which of the following is an example of a "long" bone?
    Cranium
    Rib
    Patella
    Humerus


3. What is the main substance (a protein) secreted by the main cells in cartilage that makes up the extra-cellular matrix?
    Elastin secreted by fibroblasts
    Collagen secreted by chondrocytes
    Collagen secreted by astrocytes
    Keratin secreted by fibroblasts


4. What is endochondral ossification?
    Bone growth within an area of hyaline cartilage
    Bone growth in bones where there is no cartilage precursor
    The self-destruction of bone by the bursting open of the bone cells
    A disease similar to osteoporosis


5. Which of the following is a function of cartilage?
    Both of these
    Provides the body with a rich source of potassium ions
    Neither of these
    Supports soft tissue


6. Cartilage can grow interstitially or appositionally. What is the principal difference between the two processes?
    Interstitial growth is much more important
    Appositional growth occurs only in the cartilage of the neck and trunk, whereas interstitial growth occurs all over the body
    Appositional growth involves only the early phases of cartilage formation, whereas interstitial growth happens throughout life
    Appositional growth involves growth from the surface of the cartilage only, whereas interstitial growth occurs from inside it


7. Which of the following bone markings means a hollow passage through a bone?
    Facet
    Ramus
    Sulcus
    Foramen


8. Which options(s) of the following are real types of synovial joint?
    All of them
    Saddle
    Plane
    Pivot


9. How does cartilage get its nutrients?
    From blood in capillaries passing through it
    Through diffusion of the nutrients into the ground substance surrounding the cells making up the cartilage
    It shares the nutrients delivered by capillaries to the bone nearest to it
    The cells it is comprised of are completely self-sufficient and need no nutrients delivered to them


10. Both matured cells of bone and cartilage lie in matrix cavities. What is the real name of these cavities?
    Bony pores
    Extra-cellular matrix deficit regions (ECMDR)
    Lacunae
    Osteo-chondral sites
