Scheitelbeinen
Scheitelbeinen, or parietal bones, are the paired bones that form the central portion of the skull’s roof and its upper sides. Each bone is roughly rectangular and curved, and the two meet along the sagittal suture at the skull’s midline. The external surface features the parietal eminence and the superior and inferior temporal lines, which mark attachment sites for the temporalis muscle and associated fascia.
The internal surface carries markings related to the brain and its coverings, including grooves for meningeal
Articulations: The parietal bones articulate with the frontal bone at the coronal sutures, with the occipital
Development: Parietal bones develop by intramembranous ossification. In infants, growth occurs with the presence of fontanelles
Clinical significance: Parietal bone fractures are common with blunt head trauma. Fractures at the pterion can
