Occipital bone, os occipitale, seen from right side. (The direction does not correspond to that of the bone when the skull is in its ordinary position.) The squama occipitalis is curved so as to be convex backward in the sagittal and transverse direction. Its anterior border forms the posterior periphery of the foramen occipitale magnum; the free lateral and superior borders meet in the median plane, the lower portion of each lateral border being slightly serrated as the continuation of the margo mastoidteus (]). 2); the upper portion of this border is deeply and multiply serrated and is known as the margo lambdoideus for union with the occipital margin of the parietal bone (sutura lambdoidea). Projecting from the middle of the posterior surface is seen the external occipital protuberance (protaberantia occipitalis externa). Extending lateral wan l from this protuberance on each side are the superior nuchal lines (linear nuchae superiores), convex upward, and above these the less constant supreme nuchal linos (lineae nuchae supremue). In the median plane extending toward the foramen magnum is seen the external occipital crest (crista occipitalis externa) which gives attachment to the ligamentum nuchae. From about the middle of the crest extend lateralward the two inferior nuchal lines (lineae nuchae iuferiores), also convex upward. The area for the in. occipitalis above the external protuberance and the supreme nuchal lines is called the occipital plain (planum occipitale), while that below the same is designated the nuchal plain (planum nucliale) and gives attachment to the mm. trapezius, sternocleidomastoideus, splenitis capitis, semispinalis capitis, ohliquus capitis superior, recti capitis posterioivs. * hi the anterior surface of the hone at the middle point of the cinincntia crueiata nearlv corresponding in position to the external protuberance is seen the internal occipital protuberance or protuberuutiu occipitalis interna (for the conflucns sinuuni; falx cerebri, and tentorium ccrchclli). From the internal protuberance arise three well marked grooves: one in the median line parses upward, the sulcus sagittalis ((). 1. superior longitu¬ dinal sulcus) for the sinus sagittalis superior and the falx cerebri: and one lateralward on each side, the sulcus transversus (for the sinus transversus; tentorium cerehelli). Of the two transverse sulci the right is usually wider than the left and it alone is continuous with the sulcus sagittalis. A fourth groove or re often) ridge extends to the foramen magnum and receives the sinus occipitalis.](https://iiif.wellcomecollection.org/image/b29336211_0015.jp2/full/800%2C/0/default.jpg)
