THE SKULL FROM BEHIND (norma occipitalis) (fig. 3). From this point of view the posterior ends of the parietal bones (PP), with the sagittal suture between them, are seen. Below these comes the supra-occipital bone (fig. S, 0) separated from them by the lambdoid suture which is deeply serrated and a frequent site of Wormian bones. Where the sagittal and lambdoid sutures meet is the lambda (L), and here a small Wormian bone is sometimes found, called the preinter parietal. In the mid line about a hand's breadth (24-3 in.) below the lambda is a prominence, the external occipital protuberance or inion, for the attachment of the ligamentum nuchae, while running out on each side from this are the superior curved lines which attach muscles of the neck.
