| Anatomical terminology | |
The coronal suture is a dense, fibrous connective tissue joint that separates the two parietal bones from the frontal bone of the skull.
Clinical significance
If certain bones of the skull grow too fast then premature fusion 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"
The coronal suture is derived from the paraxial mesoderm.
