Verified step by step guidance

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

Define a saddle joint: A saddle joint is a type of synovial joint where the articulating surfaces are shaped like a saddle, allowing for movements such as flexion, extension, abduction, adduction, and circumduction.

Identify the characteristics of a saddle joint: Saddle joints allow for a greater range of motion compared to hinge joints but less than ball-and-socket joints. They are biaxial, meaning they allow movement in two planes.

Examine the options provided: Review the list of joints given in the problem: Carpometacarpal joint of the thumb, Knee joint, Hip joint, and Elbow joint.

Determine which joint is a saddle joint: Recognize that the carpometacarpal joint of the thumb is a classic example of a saddle joint, allowing for the thumb's unique range of motion, including opposition.
