Step 1: Understand the anatomy of the hip joint. The hip joint is formed by the articulation of the head of the femur and the acetabulum of the pelvis. It allows a wide range of motion, including flexion, extension, abduction, adduction, rotation, and circumduction.
Step 2: Review the types of synovial joints. Synovial joints are classified into six types based on their structure and the movements they allow: ball-and-socket, hinge, pivot, saddle, plane, and condyloid.
Step 3: Compare the characteristics of each type of synovial joint. For example, ball-and-socket joints allow movement in multiple axes and planes, hinge joints allow movement in one plane (like a door hinge), pivot joints allow rotational movement, and saddle joints allow movement in two planes.
Step 4: Match the hip joint's range of motion and structure to the correct type of synovial joint. The hip joint's ability to move in multiple axes and planes aligns with the characteristics of a ball-and-socket joint.
Step 5: Confirm the answer by recalling other examples of ball-and-socket joints, such as the shoulder joint, which also allows a wide range of motion similar to the hip joint.
