Question:
Which type of joint is involved when you bend your knees and ankles?
(a) Ball and socket
(b) Hinge
(c) Pivot
Answer:
Verified
(b) Hinge
Explanation: The knee and ankle are examples of hinge joints. A hinge joint allows movement mainly in one plane, such as bending (flexion) and straightening (extension), similar to the movement of a door hinge. These joints provide controlled movement and stability. Ball and socket joints allow movement in multiple directions, while pivot joints permit rotational movement.
