The ball and socket joint (also known as the spheroid joint) is a type of synovial joint in which one rounded bone’s ball-shaped surface fits into the cup-like depression of another.
The distal bone can move about an infinite number of axes, all of which have the same common centre. The joint can now move in a variety of directions.
The hip joint, where the round head of the femur (ball) rests in the cup-like acetabulum (socket) of the pelvis, and the shoulder joint, where the rounded upper extremity of the humerus (ball) rests in the cup-like glenoid fossa (socket) of the shoulder blade, are both examples of this type of articulation.
Final Answer:
The following are some examples of ball and socket joints:
Hip joint, where the femur’s rounded head (ball) lies in the pelvis’ cup-like acetabulum (socket).
Shoulder joint, where the rounded head of the humerus (ball) lies in the shoulder blade’s cup-like glenoid fossa (socket).
