Detailed explanation-1: -Ball-and-socket joints possess a rounded, ball-like end of one bone fitting into a cuplike 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 (Figure 19.32).

Detailed explanation-2: -A ball and socket joint is an articulation between the rounded head of one bone (ball) and the concavity of another (socket). This type of joint is multiaxial: it permits flexion/extension, abduction/adduction, and rotation. The only two ball and socket joints of the body are the hips and the shoulder (glenohumeral).

Detailed explanation-3: -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.

Detailed explanation-4: -A condyle is the round prominence at the end of a bone, most often part of a joint – an articulation with another bone.

Detailed explanation-5: -A ball and socket joint is a movable joint where one bone is hooked into the hollow space of another bone. It allows movement in all directions. Example: shoulder joints.
