Verified step by step guidance

Understand the definition of a ball and socket joint: A ball and socket joint is a type of synovial joint where a spherical end of one bone fits into a cup-like cavity of another bone, allowing for multi-directional movement and rotation.

Identify the characteristics of ball and socket joints: These joints allow for the widest range of motion, including flexion, extension, abduction, adduction, rotation, and circumduction.

Review the anatomy of the hip joint: The hip joint is a ball and socket joint where the head of the femur (thigh bone) fits into the acetabulum of the pelvis, allowing for extensive movement.

Review the anatomy of the shoulder joint: The shoulder joint is another ball and socket joint where the head of the humerus (upper arm bone) fits into the glenoid cavity of the scapula, providing a wide range of motion.

Compare other joint types: Sacroiliac and pubic symphysis joints are examples of cartilaginous joints, elbow and knee joints are hinge joints, and wrist and ankle joints are examples of condyloid and hinge joints, respectively. These do not fit the ball and socket joint criteria.
