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

The coronal suture lies between the paired parietal bones and the frontal bone of the skull.

The coronal suture is likely supplied by a branch of the trigeminal nerve.

[2] The coronal suture is derived from the paraxial mesoderm.

If certain bones of the skull grow too fast then premature fusion of the sutures, craniosynostosis, may occur.
