What is an example of a fixed joint?

A fixed joint, also known as a fibrous joint, is one that allows no movement between the bones that are connected. An example of this type of joint is found in the bones of the skull, which are tightly fused together by sutures. These sutures provide structural integrity and protection to the brain, and their immobility helps maintain the shape of the head.

In contrast, the other joints listed—such as the elbow, knee, and wrist—are classified as movable joints (hinge or ball-and-socket joints) that allow for various ranges of motion, thus distinguishing them from fixed joints where there is no movement.
