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.<ref name=":0">{{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}}</ref> It runs from the pterion on each side.
=== Nerve supply === The coronal suture is likely supplied by a branch of the trigeminal nerve.<ref>{{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}}</ref>
=== 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.<ref name=":0" /> This can result in skull deformities.<ref name=":0" /> These deformities include:<ref>{{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}}</ref> * Brachycephaly (both sides) * Plagiocephaly (one side only) * Oxycephaly (both sides)
