Worked Solution & Example Answer:Bones form joints to allow different ranges of movement - Edexcel - GCSE Physical Education - Question 3 - 2020 - Paper 1
Step 1
(a) Stating a range of movement possible at each type of joint.
Answer
-
Pivot: The movement possible is rotation, as seen in the joint between the atlas and axis of the spine.
-
Hinge: The movement possible is flexion and extension, which occurs at joints like the knee and elbow.
-
Ball and socket: The movement possible is abduction and adduction, observed in joints such as the hip and shoulder.
Step 2
Step 3
Explain the importance of having short bones in the wrist for the diver in Figure 3.
Answer
Having short bones in the wrist is important for the diver because it provides increased stability and flexibility. Short bones allow for a greater range of motion, which is essential for maintaining balance and control during the dive.
Furthermore, this structure helps the diver to distribute forces more effectively when they enter the water, reducing the risk of injury while maximizing performance.
