The coronal suture is a dense, fibrous connective tissue joint that separates the two parietal bones from the frontal bone of the skull.

StructureEdit
The coronal suture lies between the paired parietal bones and the frontal bone of the skull.[1] It runs from the pterion on each side.
Nerve supplyEdit
The coronal suture is likely supplied by a branch of the trigeminal nerve.[2]
DevelopmentEdit
The coronal suture is derived from the paraxial mesoderm.
Clinical significanceEdit
If certain bones of the skull grow too fast then premature fusion of the sutures may occur.[1] This can result in skull deformities.[1] There are two possible deformities that can be caused by the premature closure of the coronal suture:
- a high, tower-like skull called "oxycephaly" or "turret skull".[1]
- a twisted and asymmetrical skull called "plagiocephaly".
