Skull (lateral view) (English)

The frontal bone articulates with the zygomatic bone (frontozygomatic suture), the greater wing of the sphenoid bone (sphenofrontal suture) and the parietal bones (coronal suture). From this lateral perspective, the squamous and petrous part of the temporal bone are visible and are separated from each other by the zygomatic process. This zygomatic process unites with the temporal process of the zygomatic bone to form the zygomatic arch. The squamous part of the temporal bone articulates with the parietal bone superiorly (squamous suture) and with the greater wing of the sphenoid bone anteriorly (sphenosquamosal suture). The squamous part of the temporal bone and the greater wing of the sphenoid bone together form the majority of the temporal fossa. The external acoustic meatus is part of the tympanic portion of the temporal bone with the styloid process situated inferior, and the mastoid process posterior to it. The pterion is a point of intersection of frontal, sphenoid, parietal, and temporal bones.On this view, the occipital bone is seen articulating with the parietal bone superiorly and the petrous part of the temporal bone inferiorly.
