What is an example of a fibrous joint?

A fibrous joint is characterized by the connective tissue that tightly binds the bones together, allowing for very limited movement, if any. One of the primary examples of a fibrous joint is found in the skull, where the bones are interconnected by sutures. These sutures are composed of dense connective tissue that fuses the cranial bones together, providing stability and protection for the brain but allowing for little to no movement between the bones.

In contrast, other types of joints exhibit different structures and functions. The knees are classified as hinge joints, allowing for flexion and extension. The shoulder is a ball-and-socket joint, permitting a wide range of motion. The spine consists of various types of joints, including facet joints which allow for movement, but the intervertebral discs themselves provide limited movement and are classified differently. Thus, the skull is the correct answer as it exemplifies the characteristics of a fibrous joint.
