Verified step by step guidance

Step 1: Understand the concept of a ball-and-socket joint. A ball-and-socket joint is a type of synovial joint where a spherical head of one bone fits into a cup-like socket of another bone, allowing movement in multiple directions including rotation.

Step 2: Review the anatomy of the listed joints. The ankle joint is a hinge joint, allowing movement primarily in one plane (dorsiflexion and plantarflexion).

Step 3: Examine the knee joint. The knee joint is a hinge joint with some rotational capability, but it does not fit the ball-and-socket structure.

Step 4: Analyze the shoulder joint. The shoulder joint (glenohumeral joint) is a ball-and-socket joint, where the spherical head of the humerus fits into the cup-like glenoid cavity of the scapula, allowing a wide range of motion.

Step 5: Confirm that the elbow joint is a hinge joint, permitting movement primarily in one plane (flexion and extension), and does not meet the criteria for a ball-and-socket joint.
