A fibrous joint is a type of joint where two 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 protect the brain and allow for growth during development. There are three main types of fibrous joints: sutures, syndesmoses, and gomphoses. Sutures are found in the skull, syndesmoses allow for slight movement between bones, such as in the ankle, and gomphoses are the joints between teeth and their sockets.
