Study Notes

Sutures of the Skull

Sagittal Suture: Connects the two parietal bones along the midline of the skull.
Metopic Suture: Occasionally found in adults, it unites the two frontal bones; its presence can vary.
Lambdoid Suture: Links the parietal bones to the occipital bone, forming the posterior part of the skull.
Squamosal Suture: Joins the squamous portion of the temporal bone with the parietal bones, located on the lateral aspect of the skull.
Coronal Suture: Provides a connection between the frontal bone and the parietal bones, situated at the front of the skull.

Main Sutures

The major sutures of the skull include the Coronal, Sagittal, Lambdoid, Squamosal, and occasionally the Metopic suture.
These sutures play a crucial role in the overall structure and growth of the cranial bones.
