Hinge joint

Pivot joint

Saddle joint

Verified step by step guidance

Step 1: Understand the question by identifying the key terms. The problem asks about a type of synovial joint that allows movement in multiple axes, and provides examples of joint types to choose from.

Step 2: Recall the definition of synovial joints. Synovial joints are characterized by a fluid-filled cavity that allows for smooth movement between articulating bones. They are classified based on the type and range of movement they allow.

Step 3: Review the characteristics of the ball-and-socket joint. This type of synovial joint allows movement in multiple axes, including flexion, extension, abduction, adduction, rotation, and circumduction. The shoulder joint is a prime example of this type of joint.

Step 4: Compare the ball-and-socket joint to the other options provided: Hinge joints allow movement in one axis (e.g., elbow), pivot joints allow rotational movement around a single axis (e.g., atlantoaxial joint), and saddle joints allow movement in two axes (e.g., thumb joint). None of these allow movement in multiple axes like the ball-and-socket joint.

Step 5: Conclude that the correct answer is 'Ball-and-socket joint,' as it matches the description of allowing movement in multiple axes and is exemplified by the shoulder joint.
