Definition

1. Noun:
   • The suture between the parietal and frontal bones of the skull: The "coronal suture" is a dense, fibrous joint connecting the frontal bone (at the front of the skull) to the two parietal bones (at the top and sides of the skull). It is one of the major sutures of the human skull.

  • In forensic anthropology, the fusion state of the coronal suture can help estimate age at death.

Advanced Usage

• "Coronal suture fusion/closure": Refers to the biological process where this fibrous joint ossifies and becomes immobile, typically occurring with age.
