Document Summary

Superior and lateral aspect of cranial vault. Four sutures mark the articulations of parietal bones with frontal, occipital, and temporal bones: Coronal suture- between parietal bones and frontal bone. Sagittal suture- between right and left parietal bones. Lambdoid suture- between parietal bones and occipital bone. Squamous (squamosal) sutures- between parietal and temporal bones on each side of skull. Most of skull"s posterior wall and posterior cranial fossa. Site of attachment for the ligamentum nuchae and many neck and back muscles. Inferolateral aspects of skull and parts of cranial floor. Superior part of nasal septum, roof of nasal cavities. Tiny irregularly shaped bones that appear within sutures. Temporomandibular joint: only freely movable joint in skull. Medially fused to form upper jaw and central portion of facial skeleton. Articulate with all other facial bones except mandible. Form part of lateral walls of nasal cavity. Formed by parts of seven bones (next slide)
