Question

Which of the following joints work as in the figure given below?

• A. Ankle and knee joints
• B. Hip and shoulder joints
• C. Ankle and wrist joints
• D. Shoulder and knee joints

Answer 1

The correct option is B

Hip and shoulder joints

In the figure, one end of a bone which is rounded and ball-like fits into a cup-like depression of another bone. E.g. Hip and shoulder joints. This type of joint helps in rotatory movement. In the shoulder joint the head of the humerus fits into a socket of the shoulder girdle and in the hip joint the large ball-like head of the femur fits into the deep socket of the hip girdle.
