<P> A suture is a type of fibrous joint that is only found in the skull . The bones are bound together by Sharpey's fibres . A tiny amount of movement is permitted at sutures, which contributes to the compliance and elasticity of the skull . These joints are synarthroses . It is normal for many of the bones of the skull to remain unfused at birth . The fusion of the skull's bones at birth is known as craniosynostosis . The term "fontanelle" is used to describe the resulting "soft spots". The relative positions of the bones continue to change during the life of the adult (though less rapidly), which can provide useful information in forensics and archaeology . In old age, cranial sutures may ossify (turn to bone) completely . The joints between the teeth (gomphoses) and the joint between the mandible and the cranium, the temporomandibular joint, form the only non-sutured joints in the skull . </P> <Ul> <Li> Plane sutures - edges of the bones are flush with each other as in a normal butt joint </Li> <Li> Limbous sutures - edges are bevelled so the plane of the suture is sloping as in a mitre joint </Li> <Li> Schindylesis - formed by two bones fitting into each other similar to a bridle joint </Li> <Li> Denticulate sutures - the edges slot into each other as in a finger joint </Li> <Li> Serrate sutures - similar to a denticulate suture but the interlocking regions are serrated rather than square . </Li> </Ul> <Li> Plane sutures - edges of the bones are flush with each other as in a normal butt joint </Li> <Li> Limbous sutures - edges are bevelled so the plane of the suture is sloping as in a mitre joint </Li>
