This questions was attempted by many candidates and their performance was fair. In part (a)(i) candidates correctly named the parts labelled I, V, VI and VII and in (a)(ii) candidates could not correctly mention movements possible at the joint between the parts labeled III and IV.
In part (b)(i) and (ii) candidates could not correctly named the type of joint between II and VIII and III and IV. In part (c) candidates correctly mentioned injury that could affect the part labelled II. In part (d) candidates also correctly mentioned mineral salts found in the human skeleton.

1(a) (i) PARTS LABELLED
I - clavicle/collar bone
V - phalanges
VI - metacarpals
VII - ulna
(ii) MOVEMENTS POSSIBLE AT THE JOINT BETWEEN PARTS
LABELLED III AND IV
- flexion
- extension
(b)(i) TYPE OF JOINT BETWEEN II AND VIII
- ball and socket/shoulder joint.
(ii) TYPE OF JOINT BETWEEN III AND IV
