The coronal suture is a dense, fibrous connective tissue joint that separates the two parietal bones from the frontal bone of the skull.
Structure
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 supply
The coronal suture is likely supplied by a branch of the trigeminal nerve. [2]
Development
The coronal suture is derived from the paraxial mesoderm.
Clinical significance
If certain bones of the skull grow too fast then premature fusion of the sutures, craniosynostosis, may occur. [1] This can result in skull deformities. [1] These deformities include: [3]
- Brachycephaly (both sides)
- Plagiocephaly (one side only)
- Oxycephaly (both sides)
