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 main range of movement is rotation. An example is the atlas and axis in the neck.
-
Hinge: The range of movement includes flexion and extension. A common example is the knee or elbow joint.
-
Ball and socket: This joint allows for a range of motion that includes abduction and adduction, such as in the hip or 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 contributes to greater flexibility and a better range of motion. This is crucial for a diver as it allows for precise positioning of the arms during dives. Additionally, short bones can provide better leverage and support when transitioning from a standing position to the dive, enabling the diver to maintain stability and control while in motion.
