Anatomical terminology [edit on Wikidata]

The coronal suture is a dense, fibrous connective tissue joint that separates the frontal and parietal bones of the skull. At birth, the bones of the skull do not meet.

Clinical significance

If certain bones of the skull grow too fast then "premature closure" of the sutures may occur. This can result in skull deformities. There are two possible deformities that can be caused by the premature closure of the coronal suture:

• a high, tower-like skull called "oxycephaly"
• a twisted and asymmetrical skull called "plagiocephaly"

coronal suture derived from the paraxial mesoderm
