Fibrous joints are a type of joint where bones are connected by dense connective tissue, primarily made up of collagen fibers. These joints are generally immovable, providing stability and strength to the skeletal system. Examples of fibrous joints include the sutures in the skull, which fuse the bones together, and the syndesmoses found between certain long bones, like the radius and ulna. There are three main types of fibrous joints: sutures, syndesmoses, and gomphoses. Sutures are found in the skull, syndesmoses allow for slight movement, and gomphoses are the joints between teeth and their sockets. Overall, fibrous joints play a crucial role in maintaining the structure and integrity of the skeleton.
