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, saddle, plane, condyloid, and ball-and-socket joints.

Identify the characteristics of a ball-and-socket joint: A ball-and-socket joint allows for rotational movement and movement in multiple planes. It consists of a spherical head (ball) fitting into a cup-like depression (socket). This structure allows for a wide range of motion, including flexion, extension, abduction, adduction, and rotation.

Review the anatomy of the hip joint: The hip joint is a classic example of a ball-and-socket joint. The head of the femur (thigh bone) acts as the ball, and the acetabulum of the pelvis acts as the socket. This joint allows for extensive movement in various directions.

Compare with other joints: The elbow joint is a hinge joint, allowing movement primarily in one plane (flexion and extension). The ankle joint is a complex hinge joint, allowing for dorsiflexion and plantarflexion. The knee joint is a modified hinge joint, allowing for flexion, extension, and slight rotation.

Conclude with the correct identification: Based on the characteristics and examples provided, the hip joint is the correct example of a ball-and-socket joint among the options given.
