The coronal suture is the serrated interlocking joint found between the frontal bone and the pair of parietal bones of the skull. It is one of the prominent sutures of the skull, easily identifiable from both the lateral and superior views. It is a fibrous (suture) joint, that has no movement (synarthrosis). It extends between the two pterions ...
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 is a dense and fibrous association of connection tissue located between the frontal and parietal bones of the skull. At birth, the sutures decrease in size (molding) and make the skull smaller. In children, the suture enables the skull to expand with the rapidly growing brain. The suture will close and fuse around age 24.
The coronal suture is the cranial suture formed between the two parietal bones and the frontal bone. At the junction of coronal, sagittal and frontal sutures, the anterior fontanelle is located which is open at birth and usually fuses at around 18-24 months after birth.
The coronal suture joins the sphenoparietal suture superiorly, the sphenofrontal suture anteriorly, the sphenosquamous suture inferiorly, and the squamous suture posteriorly. Due to the extensiveness of the articulations at the pterion, this portion of the skull is weaker than other parts, and therefore more vulnerable to fracture.
The coronal suture separates the frontal bone and the parietal bone. The coronal and the sagittal sutures converge into the bregma. The sagittal and lambdoid sutures are also visible from this angle. Review the bones of the skull with this quick, integrated quiz.
Sutures. The main sutures of the skull are the coronal, sagittal, lambdoid and squamosal sutures. The metopic suture (or frontal suture) is variably present in adults. Coronal suture - unites the frontal bone with the parietal bones. Sagittal suture - unites the 2 parietal bones in the midline. Lambdoid suture - unites the parietal bones with ...
