Left parietal bone (Os parietale)
Educational content only — not medical advice.
Anatomy
The left member of the paired parietal bones: flat with a concave internal surface, forming the left side and roof of the cranial vault; it joins the right parietal at the sagittal suture and the frontal, temporal and occipital bones at their sutures, and its inner surface is grooved by the middle meningeal artery and the sagittal venous sinus.
Clinical notes
Left parietal fractures carry the same middle-meningeal-artery bleeding risk; in newborns, birth trauma here can cause parietal cephalhaematoma.
