Which structure is an example of a hinge joint? skull wrist knee hip description?

The correct answer is the knee.

A hinge joint, also known as ginglymus, is a joint in that allows bone movement in only one direction (motion only in one plane). The articular surfaces of the bones are connected by collateral ligaments. The best example of this type of joint is the interphalangeal joints of the hand. The knee also has hinge joints but less typical, because it allows a slight degree of rotation or of side-to-side movement in certain positions of the limb.
