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.{{Cite book|last=Carlson|first=Bruce M.|chapter-url=https://www.sciencedirect.com/science/article/pii/B9781455727940000097|title=Human Embryology and Developmental Biology|date=2014-01-01|publisher=Saunders|isbn=978-1-4557-2794-0|edition=5th|pages=156–192|language=en|chapter=9 - Integumentary, Skeletal, and Muscular Systems|doi=10.1016/b978-1-4557-2794-0.00009-7}} It runs from the pterion on each side.
= Nerve supply =
The coronal suture is likely supplied by a branch of the trigeminal nerve.{{Cite book|last1=Barral|first1=Jean-Pierre|chapter-url=https://www.sciencedirect.com/science/article/pii/B9780702031007500057|title=Manual Therapy for the Cranial Nerves|last2=Croibier|first2=Alain|date=2009-01-01|publisher=Churchill Livingstone|isbn=978-0-7020-3100-7|pages=7–14|language=en|chapter=2 - Characteristics of cranial nerves}}
= 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. This can result in skull deformities. These deformities include:{{Cite web |date=2015 |title=Craniosynostosis |url=https://www.childrensmn.org/educationmaterials/childrensmn/article/15941/craniosynostosis/ |access-date=November 1, 2023 |website=Children's Hospitals and Clinics of Minnesota}}
