If asked which bones the Lambdoid suture connects, which pair is correct?

• A. Parietal and Frontal
• B. Parietal and Occipital
• C. Parietal and Temporal
• D. Frontal and Occipital

Answer: (B)

Sutures are immovable joints between skull bones. The lambdoid suture runs along the back of the skull and marks the boundary where the occipital bone meets the parietal bones. So, the bones connected by this suture are the parietal bones with the occipital bone. Other sutures tie together different pairs, like coronal between frontal and parietal, sagittal between the two parietal bones, and squamous between temporal and parietal. The lambdoid suture’s name reflects its lambda-like shape.
