  1. 1What is an articulation?
    1. AWhere two bones meet at a joint.
    2. BA pivot point.
    3. CCartilaginous ends moving against each other.
  2. 2Soft tissue in joints has no organic component.
    1. ATrue
    2. BFalse
  3. 3Choose the FALSE statement about cartilage.
    1. ACartilage is soft tissue.
    2. BHyaline cartilage is the same as articular cartilage.
    3. CFibrocartilage is what the epiphyseal plate is made from.
    4. DFibrocartilage has a different histological structure from hyaline cartilage.
  4. 4Choose the correct statements about cartilage histology.
    1. AThe chondrocytes live in lacunae.
    2. BCartilage is composed mainly of collagen fibres.
    3. CCartilage is white due to fatty acids.
    4. DCartilage acquires nutrients via diffusion as it is not vascular.
  5. 5Diffusion of nutrients into cartilage is achieved via 'loading', regular joint movement/activity
    1. ATrue
    2. BFalse
  6. 6Hyaline cartilage is [blank_start]amorphous[blank_end], with [blank_start]little[blank_end] collagen content, and a [blank_start]high[blank_end] water content, that resists [blank_start]compression.[blank_end]
    Fibrocartilage has [blank_start]many[blank_end] bundles of collagen, and resists [blank_start]tension.[blank_end] The orientation of these fibres are aligned in the direction of stress and so it also resists [blank_start]compression[blank_end], making it specialised.
    1. Aamorphous
    2. Blittle
    3. Chigh
    4. Dcompression.
    5. Emany
    6. Fsparse
    7. Gtension.
    8. Hcompression
    9. Itension
  7. 7Lack of bony congruence is made up for by hyaline cartilage moulding to the articulations of synovial joints.
    1. ATrue
    2. BFalse
  8. 8Hyaline cartilage remodels.
    1. ATrue
    2. BFalse
  9. 9The more bony congruence there is, the more soft tissue support is needed.
    1. ATrue
    2. BFalse
  10. 10The menisci are convexly shaped and diffuse forces through the bones of the knee.
    1. ATrue
    2. BFalse

Information
