The |lambdoid suture| joins the two |parietal bones| to the |occipital bone| in the back of the |skull|. The intersection of the |sagittal suture|, joining the two |parietal bones| together, and the |lambdoid suture| forms a tripartite shape, resembling the Greek letter "lambda," and giving the suture its shape. The lower ends of the |lambdoid suture| extend to the |mastoid processes| of the |temporal bones|, joining them to the |occipital bone|.
