Skull & Cranial Anatomy
Coronal suture
The coronal suture runs side-to-side across the top of the skull, separating the frontal bone from the parietal bones.
In short: Coronal suture
- It crosses the skull from side to side.
- It separates the frontal and parietal bones.
- It is normal skull anatomy.
- It is a landmark separating the front and middle of the skull.
What it is
It is the side-to-side suture across the top of the skull, separating the frontal bone (front) from the parietal bones (middle). It is one of the major cranial sutures.
Understanding Coronal suture
It is an anatomical landmark separating the front and middle of the skull and is part of normal cranial structure. Like other sutures, it allows the skull to grow and is distinct from the abnormal opening of an encephalocele.
Why it matters
Understanding the coronal suture helps families read descriptions that locate findings relative to normal skull landmarks.
Common questions
Which bones does it separate?

Where does it run?
Side-to-side across the top of the skull.
Bottom line
The coronal suture separates the frontal bone from the parietal bones across the top of the skull.
