Verified step by step guidance

Step 1: Understand the concept of a multiaxial joint. Multiaxial joints are synovial joints that allow movement in multiple planes or axes, such as flexion/extension, abduction/adduction, and rotation.

Step 2: Review the anatomy of the listed joints (ankle, shoulder, knee, and elbow) to determine which one fits the definition of a multiaxial joint. For example, the shoulder joint (glenohumeral joint) allows movement in all three planes, making it multiaxial.

Step 3: Compare the shoulder joint to the other options. The ankle joint primarily allows movement in two planes (dorsiflexion/plantarflexion and inversion/eversion), making it biaxial. The knee joint primarily allows flexion and extension, with limited rotation, making it uniaxial or slightly biaxial. The elbow joint allows flexion and extension, making it uniaxial.

Step 4: Confirm that the shoulder joint is the correct answer because it fits the definition of a multiaxial joint, allowing movement in multiple axes.

Step 5: Conclude that the shoulder joint is the correct example of a multiaxial joint based on its anatomical structure and range of motion.
