Sutures

The sutures of the skull, are fibrous joints where two two cranial bones meet.

The following are examples of the sutures of the skull and the bones that they join:

1. Coronal Suture - between the frontal bone and parietal bone

2. Lambdoid Suture - between the parietal bone and the occipital bone

3. Squamosal suture – between the parietal and the temporal bone

4. Sagittal Suture - between the two parietal bones

In neonates, the incompletely fused suture joints give rise to membranous gaps between the bones, known as fontanelles.
