What type of joint allows for the greatest range of motion?

  1. Hinge joint

  2. Ball-and-socket joint

  3. Pivot joint

  4. Fixed joint

The correct answer is: Ball-and-socket joint

The ball-and-socket joint allows for the greatest range of motion due to its unique structure. This type of joint consists of a spherical head of one bone that fits into a cup-like socket of another bone, enabling movement in several directions. Specifically, ball-and-socket joints provide motion in multiple planes: flexion and extension, abduction and adduction, and rotation. This contrasts with other types of joints. For instance, hinge joints allow for movement primarily in one direction, similar to the opening and closing of a door, limiting motion to flexion and extension. Pivot joints permit rotation around a single axis, providing movement in one plane, while fixed joints, such as those in the skull, do not permit any movement at all. Therefore, the design and functionality of the ball-and-socket joint make it the most versatile and capable of extensive motion.
