What is the suture between parietal and temporal?
Squamosal suture: the suture between the temporal and parietal bones.
What is temporal suture?
The parietotemporal or parietomastoid suture represents the articulation between the parietal and temporal bones posteriorly. Anteriorly, they articulate at the squamosal suture.
What suture divides the parietal bones?
Sagittal suture
Sagittal suture, runs longitudinally across the skull from the occipital to the frontal bone and separates the parietal bones from one another.
What is the parietal suture?
The parietal bones are joined by the sagittal suture. This suture runs along the top of the head down to the back of the skull. The coronal suture attaches the parietal bones to the frontal bones, and the lambdoid suture attaches the parietal bones to the occipital bone at the back of the head.
What is lambdoid suture?
The lambdoid suture (or lambdoidal suture) is a dense, fibrous connective tissue joint on the posterior aspect of the skull that connects the parietal bones with the occipital bone. It is continuous with the occipitomastoid suture. Its name comes from its lambda-like shape.
What are the 17 sutures of the skull?

What are the 6 sutures of the skull?
c, coronal suture; s, sagittal suture; l, lambda suture; f, frontal suture; pf, posterior frontal suture.
What is the function of the temporal bone?
The function of the temporal bone In addition to forming the external auditory canal, the temporal bone houses the cockles, canals, and hearing organs. It also protects the middle and inner ear structures, which are more delicate.
What is temporal bone?
The temporal bone is a thick, hard bone that forms part of the side and base of the skull. This bone protects nerves and structures in the ear that control hearing and balance.
What is the occipital suture?
The petro-occipital suture is the junction between the occipital bone and the petrous part of the temporal bone. The spheno-occipital suture articulates the sphenoid bone and the occipital bone. The petrosquamous suture is the interosseous border the petrous part and the squamous part of the temporal bone.
