Gross anatomy
The parietal bone has four borders, four angles, and external/internal surfaces.
The four borders are:
- frontal
- sagittal
- occipital (half of lambdoid suture)
- squamous temporal
The four angles are:
- sphenoid
- mastoid
- occipital
- frontal
The external surface is convex and smooth and has several features:
- parietal eminence
- superior temporal line for attachment of temporalis fascia
- inferior temporal lines for attachment of temporalis muscle
- parietal foramen contains an emissary vein to superior sagittal sinus
The internal surface is concave and contains grooves for the middle meningeal vessels and the sagittal sulcus.
Articulations
The parietal bone articulates with five other bones:
- the frontalbone via the coronal suture
- the sphenoidbone greater wing via the pterion
- the temporalbone via the squamous suture
- the occipitalbone via the lambdoid suture
- the contralateral parietal bone via the sagittal suture
