Study Notes
Cranial Sutures
- Cranial sutures are made of fibrous connective tissue, primarily collagen.
- They're fixed, immovable, and strengthen with age.
- By the age of 2, sutures start to fuse, becoming permanently hardened.
Coronal Suture
- Found where the crown sits, uniting the frontal and parietal bones.
Sagittal Suture
- Located on top of the skull, uniting the left and right parietal bones.
Lambdoid Suture
- Found at the back of the skull, it joins the parietal and occipital bones.
Squamosal Suture
- Located on the side of the skull, it connects the squamous part of the temporal bone with the parietal bones.
Metopic Suture
- If present, this suture joins two frontal bones, situated at the anterior of the skull.
