The coronal suture is a simple joint that unites the frontal and parietal bones of the skull.
It is one of several 'sutures', which are a type of immovable joint that exists only between the skull (or 'cranial') bones.
These sutures are fibrous joints composed of a thin layer of dense fibrous connective tissues. The irregular interlocking edges of the bones attached by these sutures contribute to the overall strength of the joints and so and reduce the risk of fracture due to impacts or other possible damage.
See notes about, and labelled diagrams of, all human cranial and facial bones on one page.
