Ball and Socket Joint

The ball and socket joint (or spheroid joint) is a type of synovial joint in which the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone. The distal bone is capable of motion around an indefinite number of axes, which have one common center.

A ball-and-socket joint consists of the ball-like surface of one bone fitting into a cuplike depression of another bone.

Such joints are triaxial, permitting movements around three axes

  • Flexion–extension,
  • Abduction–adduction
  • Rotation
  • Circumduction

Examples of ball-and-socket joints are 

  • Shoulder Joint
  • Hip joints.

At the shoulder joint, the head of the humerus fits into the glenoid cavity of the scapula. At the hip joint, the head of the femur fits into the acetabulum of the hip bone.
