What separates the parietal and temporal bones?
The squamous suture separates the temporal and the parietal bones. The lambdoid suture separates the parietal and occipital bones.
Where parietal bones connect with temporal bones?
Squamosal suture
Squamosal suture: the suture between the temporal and parietal bones.
What is the function of parietal bone?
The function of the cranium, and hence the parietal bones, is to protect the underlying fragile brain. The parietal bone is slightly curved and has a quadrilateral shape. It has two surfaces, four borders and four angles. The borders articulate with the neighbouring skull bones to form various cranial sutures.
What bones does the parietal bone articulate with?
The parietal bone articulates with five other bones:
- the frontal bone via the coronal suture.
- the sphenoid bone greater wing via the pterion.
- the temporal bone via the squamous suture.
- the occipital bone via the lambdoid suture.
- the contralateral parietal bone via the sagittal suture.
How do you know if you have a parietal bone?
The most distinctive features on the external, or ectocranial surface of the parietal are the parietal striae, distinct thin furrows that make it seem like someone has raked a sharp comb up and back along the squamosal border of the bone.
What edge is missing from the parietal bone?
ɪtəl/) are two bones in the skull which, when joined together at a fibrous joint, form the sides and roof of the cranium. In humans, each bone is roughly quadrilateral in form, and has two surfaces, four borders, and four angles….

What type of bone 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.
Can skull bone regenerate?
Conclusions: This case report shows that cranial bone regeneration is possible in children older than 6 years old, bypassing the need for cranioplasty after decompressive craniectomy.
What is CT temporal bone?
Temporal bone CT is a limited kind of head CT that focuses on the lower part of the skull and the surrounding soft tissues, and is often used in patients with hearing loss, chronic ear infections, and middle and inner ear diseases.
