Which suture is between the parietal bone and the frontal bone?

Which suture is between the parietal bone and the frontal bone?

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

Answer: (A)

Cranial sutures are fibrous joints that join skull bones and allow growth during development. The suture that sits between the frontal bone at the front of the skull and the parietal bones on the sides is the coronal suture, which runs across the top of the skull. The sagittal suture lies along the midline between the two parietal bones, the squamous sutures connect the parietal bones to the temporal bones on each side, and the lambdoid suture links the parietal bones to the occipital bone at the back. So, the boundary between the frontal and parietal bones is the coronal suture.
