A hinge joint is specifically designed to allow movement primarily in one direction, similar to the way a door opens and closes. This type of joint permits flexion and extension, providing a simple back-and-forth motion. Examples of hinge joints in the human body include the elbows and knees. These joints are structured in such a way that they restrict movement to a single plane, enhancing their efficiency for the specific types of motions needed for everyday activities.

In contrast, a ball-and-socket joint allows for multidirectional movement, enabling rotation as well as the ability to move in multiple planes. A pivot joint facilitates rotation around a single axis, allowing for movements like turning the head side to side. Gliding joints, on the other hand, allow for sliding movements between flat surfaces. Each of these types provides different ranges of motion, whereas the hinge joint is uniquely suited for unidirectional movement.
