Fibrous joints examples
1. Suture – thin layer of dense, fibrous connective tissue that joins skull bones.
– Sutural ligament
– Irregular edges add strength
– Some sutures are replaced by bone as adults: This is called a synostosis.
– Fontanels in children
2. Gomphosis – cone-shaped peg fits into socket – roots of teeth held in by periodontal ligaments
3. Syndesmosis – amphiarthrosis
– A fibrous joint in which there is more fibrous connective tissue and bones are not held together as tightly as a suture
– Forms an interosseous membrane or ligament
