Verified step by step guidance

Understand the types of synovial joints: Synovial joints are classified into several types based on their shapes and the movements they allow. The main types include hinge, pivot, ball and socket, saddle, plane, and condyloid joints.

Identify the characteristics of ball and socket joints: These joints allow for a wide range of motion in multiple directions. They consist of a spherical head fitting into a cup-like socket, allowing for rotational movement and movement in all planes.

Recognize examples of ball and socket joints: The shoulder joint (glenohumeral joint) and the hip joint (acetabulofemoral joint) are classic examples of ball and socket joints. They allow for movements such as flexion, extension, abduction, adduction, and rotation.

Differentiate from other joint types: Hinge joints, like the elbow and knee, allow movement primarily in one plane (flexion and extension). Pivot joints, such as the atlantoaxial joint in the neck, allow for rotational movement. Saddle joints, like the thumb joint, allow for movement in two planes.

Conclude by matching the joint type to the examples: Given the characteristics and examples, the shoulder and hip joints are best classified as ball and socket joints due to their structure and range of motion.
