Parietal Bone

Parietal Bone The structure indicated is the parietal bone of the skull. The parietal bone is one of 8 bones which form the calvaria (the part of the skull which contains the brain). The calvaria consists of: 2 parietal bones 2 temporal bones Frontal bone Sphenoid bone Ethmoid bone Occipital bone The parietal bone articulates anteriorly with the frontal bone at the coronal suture. Inferiorly it articulates with the temporal bone at the squamous suture. Posteriorly it articulates with the occipital bone via the lamboid suture. It has a small articulation with the sphenoid bone via the sphenoparietal suture at …

Squamous Suture

Squamous Suture The structure indicated is the squamous suture of the skull. Sutures are junctions between the bones of the skull – they are a type of fibrous joint, bound together by Sharpey’s fibres. The squamous suture forms the joint of the skull between the squamous part of the temporal bone and the inferior aspect of the parietal bone. Posteriorly, the squamous suture becomes the parietomastoid suture where the mastoid process articulates with the parietal bone. Anteriorly, the squamous suture extends towards pterion.
