Question 1.

Which type of joint is involved when you bend your knees and ankles? Class 9

(i) Ball and socket

(ii) Hinge

(iii) Pivot

Answer:

(ii) Hinge

The knee and ankle joints are hinge joints. Like a door hinge, they allow movement in one direction only - bending (flexion) and straightening (extension). They do not allow sideways or circular movements. This is similar to the elbow joint, which is also a hinge joint.
