    Answer

     

    Answer outline and marking scheme for question: 3

    a) To get your 2 marks you have to state that only flexion and extension take place at a hinge joint.

    (2 marks)

    b) You receive 1 mark for stating that when a muscle contracts the muscle shortens and 1 mark for saying that when a muscle relaxes it lengthens.

    (2 marks)

    c) Remember, fast twitch fibres contract with a lot of force and tire quickly. So, to get your 1 mark you need to say that the athlete would be more suited to activities that need bursts of strength and power, for example, sprinting, weightlifting.

    (1 mark)

    d) Give yourself 1 mark for naming each type of joint and another for an appropriate example to go with it, up to 4 marks in total.

    1. Ball and socket joint, for example, hip and shoulder
    2. Pivot joint, for example, joint between atlas and axis, joint between radius and ulna
    3. Saddle joint, for example, base of thumb
    4. Condyloid joint, for example, wrist, joint between the base of skull and atlas
    5. Gliding joint, for example, joints between carpals and tarsals, joints between vertebrae

     

    (4 marks)

    e) If you have stated that they are contracting isometrically you get 1 mark.
