What are the three types of fibrous joints?

The fibrous joints are mostly immovable. The three types of fibrous joints are sutures, syndesmoses, and gomphoses. Sutures provide protection for the brain and are only found in the adult skull. They are immovable joints. A syndesmoses joint is a joint where the bones do not touch each other and are held together by fibrous connective tissue. One example of a syndesmoses joint is the distal articulation between the tibia and fibula. A gomphosis joint (from the Greek gomphos, meaning “bolt”) is composed of a peg and socket. The only gomphoses joints in the human body are the teeth. The roots of the teeth articulate with the sockets of the alveolar processes of the maxillae and mandible.
