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.

Usage

• The term is used in anatomical, medical, and anthropological contexts to describe a specific cranial feature.
• It is typically used as a singular noun.

Examples

• Noun:
  • The infant's coronal suture is still open to allow for brain growth.
  • In forensic anthropology, the fusion state of the coronal suture can help estimate age at death.
  • The surgeon made an incision along the line of the coronal suture.

Advanced Usage

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

Variants and Related Words

• Suture (n): In anatomy, a type of immovable joint found only between skull bones.
• Frontal bone (n): The bone forming the forehead and the upper part of the eye sockets.
• Parietal bone (n): Either of the two bones forming the sides and roof of the skull.

Synonyms

• Frontoparietal suture: A less common synonym that explicitly names the bones it connects.

Related Phrases

• Cranial suture: The general category of joints to which the coronal suture belongs. Other major cranial sutures include the sagittal suture and the lambdoid suture.
