Question 1 Report
(a) Name one joint in the body that is classified as a condyloid joint. [1]
(b) State two types of movement that can occur at a ball and socket joint. [2]
(c) A volleyball player uses several different types of joint during a game. Describe how three named joints are used during a volleyball spike. State the type of joint and the movement that occurs at each. [6]
Answer Details
(a) The wrist is classified as a condyloid joint. [1] A condyloid joint allows movement in two planes (flexion/extension and abduction/adduction) but not full rotation.
(b) Two types of movement at a ball and socket joint (any two): [2]
- Flexion [1]
- Extension [1]
- Abduction [1]
- Adduction [1]
- Rotation [1]
- Circumduction [1]
(c) Three joints used during a volleyball spike, with the joint type and movement at each: [6]
- Shoulder - a ball and socket joint. During the spike, the arm moves through abduction (lifting away from the body) and then flexion (swinging forward and downward to strike the ball). [1+1]
- Elbow - a hinge joint. The forearm extends at the elbow as the player straightens the arm to make contact with the ball above the net. [1+1]
- Wrist - a condyloid joint. The wrist flexes (snaps forward) on contact with the ball, adding topspin and directing the ball downward into the opponent's court. [1+1]
