Question

Ball and Socket Joint Present in:

• A. Knee
• B. Elbow
• C. Finger
• D. Shoulder Joint and Hip Joint

Hint:

Ball and socket joints allow for the greatest range of motion, enabling movements like rotation, flexion, and extension in multiple directions. The shoulder and hip are the primary examples.

Answer 1

The Correct Option is D

Solution:

The ball and socket joint is a type of synovial joint that allows the widest range of motion in all directions. This joint is characterized by the spheroid shape of the articulating bone, allowing it to rotate within the socket of another bone. Among the options provided, this type of joint is found in:

• Shoulder Joint: The head of the humerus fits into the glenoid cavity of the scapula, forming a ball and socket joint.
• Hip Joint: The head of the femur fits into the acetabulum of the pelvis, forming another key ball and socket joint.

These joints facilitate a wide range of movements, including rotation, which is not possible in hinge joints found in the knee, elbow, and finger.
