The Lambda landmark is formed where which sutures meet?

• A. Sagittal Suture and Metopic Suture
• B. Coronal Suture and Sagittal Suture
• C. Lambdoid Suture and Coronal Suture
• D. Lambdoid Suture and Sagittal Suture

Answer: (D)

The lambda landmark marks the junction where the sagittal suture meets the lambdoid sutures, at the back of the skull. The sagittal suture runs along the midline between the two parietal bones, while the lambdoid sutures connect the occipital bone to the parietal bones. Their meeting point forms lambda, which in infants sits near the posterior fontanelle. This is different from the bregma, where sagittal meets coronal sutures, or other sutural intersections.
