Pivot joint

Ball-and-socket joint

Hinge joint

Saddle joint

Verified step by step guidance

Step 1: Begin by understanding the classification of joints. Synarthrosis joints are immovable joints, while synovial joints are freely movable joints. Synovial joints are further categorized based on their range of motion and structure.

Step 2: Review the types of synovial joints. The main types include pivot joints, hinge joints, saddle joints, and ball-and-socket joints. Each type allows for specific movements based on its anatomical structure.

Step 3: Focus on the ball-and-socket joint. This type of synovial joint is characterized by a spherical head fitting into a cup-like socket, allowing movement in all directions, including flexion, extension, abduction, adduction, rotation, and circumduction.

Step 4: Compare the ball-and-socket joint to other synovial joints listed in the problem. For example, pivot joints allow rotational movement, hinge joints permit movement in one plane (like a door hinge), and saddle joints allow movement in two planes but not all directions.

Step 5: Conclude that the ball-and-socket joint is the correct answer because it is the only type of synovial joint that allows movement in all directions, making it distinct from the other options provided.
