Question

Which of the following part(s) has ball and socket joints?

• A. Shoulder joints
• B. Hip joints
• C. Wrist joints
• D. Both A and B

Answer 1

Answer: (D)

Both A and B

The ball and socket type of joint comprises a cup-like bone depression with a ball-like bone surrounded by cartilage. These joints provide the maximum strength and rotation (full circle/ 360${}^o$) as compared to other joints of the body. They are present in the pelvic (hip region) and the pectoral (shoulder region) of the body.

Hence, the shoulder joints and the hip joints have ball and socket type of joints, whereas the wrist joints are an example of hinge joints (maximum rotation of 180${}^o$, along with a single axis).
