The suture that separates the Parietal and Temporal bones is called which?

• A. Coronal suture
• B. Sagittal suture
• C. Squamous suture
• D. Lambdoid suture

Answer: (C)

The suture between the parietal bone and the temporal bone is the squamous suture. This seam runs along the lateral side of the skull where the temporal bone’s squamous part meets the parietal bone, forming the boundary between those two bones. It’s distinct from other sutures: the coronal suture lies between the frontal bone and the parietal bones, the sagittal suture sits between the two parietal bones, and the lambdoid suture connects the parietal bones to the occipital bone. So, identifying the squamous suture reflects recognizing the specific parietal-temporal articulation.
