This article is about joints in the bones of the cranium. For stitches holding tissues together, see Surgical suture. For natural structures of a wide range of animals, see Suture (anatomical). For other uses, see Suture (disambiguation).

A suture is a type of fibrous joint which only occurs in the skull (or "cranium"). They 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.^[1]

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.^{[verification needed]}

The joint between the mandible and the cranium, the temporomandibular joint, forms the only non-sutured joint in the skull.

List of sutures[edit source | edit]

Most sutures are named for the bones they articulate, but some have special names of their own.

Primarily visible from the side (norma lateralis)[edit source | edit]

Coronal suture - between the frontal and parietal bones
Lambdoid suture - between the parietal and occipital bones and continuous with the occipitomastoid suture
Occipitomastoid suture - between the occipital and temporal bones and continuous with the lambdoid suture
Parietomastoid suture
Sphenofrontal suture
Sphenoparietal suture
Sphenosquamosal suture
Sphenozygomatic suture
Squamosal suture - between the parietal and the temporal bone
Zygomaticotemporal suture
Zygomaticofrontal suture

Primarily visible from front (norma frontalis) or above (norma verticalis)[edit source | edit]

Frontal suture / Metopic suture - between the two frontal bones, prior to the fusion of the two into a single bone
Sagittal suture - along the midline, between parietal bones

Primarily visible from below (norma basalis) or inside[edit source | edit]

Frontoethmoidal suture
Petrosquamous suture
Sphenoethmoidal suture
Sphenopetrosal suture

Bone sialoprotein (BSP) is a multifunctional extracellular matrix protein found in mineralized tissues, including bone, cartilage, tooth root cementum (both acellular and cellular types), and dentin. In order to define the role BSP plays in the process of biomineralization of these tissues, we analy
