Examples of fixed joints include the joints between the bones in the skull and the joint where the radius and ulna bones meet in the lower arm. Fixed joints, also known as fibrous joints, are places where two bones come together in the body but are unable to move. This type of joint is held together by fibrous connective tissue rather than ligaments and tendons.Continue Reading
There are three different types of fixed joints in the body: sutures, syndesmoses and gomphoses. Sutures are the junctions between the skull bones. These joints are slightly mobile while a person is an infant, allowing the skull to expand as the brain grows. The sutures become completely rigid by the time a child is a toddler, thus protecting the brain from damage.
Syndesmoses are fixed joints between two long bones. There are two places where syndesmoses are found in the body: between the radius and ulna in the arm and between the fibular and tibia in the leg. A small amount of motion does actually occur in syndesmoses joints, but since they are connected by fibrous tissue, they are still technically considered fixed joints.
The final type of fixed joint, gomphoses, are the joints between the tooth roots and the mandible or maxillary bones. These joints are completely immobile, and each tooth is attached to the bone by fibrous connective tissue.Learn more about Bones
