Detailed explanation-1: -Ball-and-socket joints possess a rounded, ball-like end of one bone fitting into a cup-like socket of another bone. This organization allows the greatest range of motion, as all movement types are possible in all directions. Examples of ball-and-socket joints are the shoulder and hip joints.

Detailed explanation-2: -Shoulder Joint. The shoulder joint is called the glenohumeral joint. This is a ball-and-socket joint formed by the articulation between the head of the humerus and the glenoid cavity of the scapula ([link]). This joint has the largest range of motion of any joint in the body.

Detailed explanation-3: -The joint with the greatest range of motion is the ball-and-socket joint. At these joints, the rounded head of one bone (the ball) fits into the concave articulation (the socket) of the adjacent bone (see Figure 9.4. 3f).

Detailed explanation-4: -Ball and socket joints: these joints allow the widest range of movement, and permit side to side, back and forth and rotational movements (tri-axial – flexion and extension, abduction and adduction, rotation, circumduction – sagittal, frontal and transverse planes).

Detailed explanation-5: -ball-and-socket joint, also called spheroidal joint, in vertebrate anatomy, a joint in which the rounded surface of a bone moves within a depression on another bone, allowing greater freedom of movement than any other kind of joint.
