The lambdoid suture is the serrated interlocking joint between the two parietal bones and the occipital bone of the skull, whose name derives from its resemblance to the Greek uppercase letter lambda (Λ). It is one of the prominent sutures of the skull, easily identifiable on the posterior and lateral aspects. It is a fibrous (suture) joint, that has no movement (synarthrosis).
It extends between the two asterion on either side of the skull. The sagittal suture typically connects to the midpoint of the lambdoid suture at apex of the occipital bone, forming the lambda, which resembles the lowercase Greek letter lambda (λ). This point marks the location of the posterior fontanelle in the developing skull. Small bones called sutural (Wormian) bones are most commonly formed within the lambdoid suture.
