Gliding joints allow motion in which total amount and plane?

• A. A limited amount of motion in only one plane
• B. No motion
• C. Infinite motion
• D. A large amount of motion

Answer: (A)

Gliding joints move by sliding surfaces past one another, which means the motion is translational, non-rotational, and confined to a single plane with only a small range. Because the articular surfaces are flat and the joint is designed for slipping rather than bending, the amount of movement is limited. That’s why the description of a limited amount of motion in only one plane fits best. Examples include joints between carpal bones and the acromioclavicular joint, which glide rather than hinge or spin. They do not provide zero motion, nor do they allow large or infinite movement.
