What characterizes synarthroses joints?

Synarthroses joints are characterized by their immobility. These joints are connected by dense connective tissues, which may consist of fibrous tissue or cartilage. Common examples include sutures found in the skull and the gomphosis joint, which secures teeth to their socket. Because of their structure, synarthroses serve essential functions such as providing stability and protection to critical structures, especially in the skull where immovable joints protect the brain.

While other types of joints, such as diarthroses, are designed to allow for a wide range of motion, synarthroses prioritize the integrity and stability of the areas they connect. This makes them crucial in areas of the body where movement could compromise function or safety. Joints that allow limited or free movement do not fit the definition of synarthroses, reinforcing the understanding of their unique role in the musculoskeletal system.
