Skull & Cranial Anatomy
Sagittal suture
The sagittal suture runs front-to-back along the midline top of the skull, between the two parietal bones.
In short: Sagittal suture
- It is a major midline suture.
- It separates the two parietal bones.
- It is normal skull anatomy.
- It is a landmark for describing locations on top of the head.
What it is
It is the midline top suture of the skull, running from front to back between the two parietal bones. It is one of the major cranial sutures.
Understanding Sagittal suture
It is a landmark of normal skull anatomy and helps describe locations on the top of the head, such as where a parietal encephalocele sits. Like other sutures, it is a normal flexible joint that allows skull growth, not a defect.
Why it matters
Understanding the sagittal suture helps families follow descriptions of where a top-of-head lesion is located relative to normal skull landmarks.
