This question was  attempted by many candidates and candidates performed poorly.  In part (a) candidates could not identify the  diagram as lower limb the candidates were confused the lower limb with upper  limb candidates named the labelled part  III as humerus instead of femur.   While some named radius, biceps, triceps instead of tibia, quadriceps  and gastronemius.  In part (b) candidates  mentioned joint between II and III as shoulder joint instead of ball &  socket/hip joint while III and VIII as elbow joint instead of hinge joint knee  joint:  In part (c) candidates successful  list injuries that could occur in the parts of the lower limb.
                    The expected answers were  as follows:
                    4   (a)    Naming the parts labelled
                                  I        -     vertebral column/lumbar vertebra
             II        -     pelvic bone/girdle/pelvis
            III        -     Femur
            IV       -      Rectus femoris/quadriceps
            V        -      Tibialis/Tibia muscles
            VI      -       Tarsal bones
            VII     -       soleus gastrocnemius/soleus
            VIII    -       Tibia
            IX      -        Biceps femoris/hamstrings
            X       -        Gluteus maximus.
                      (b)     Joints at the lower limb
                    (i)Naming the joint  between II and III
                    
                      -    Ball and socket/hip joint.
 
                    
                    (ii) Naming the Joint between III and VIII
