Anatomical terms of bone [edit on Wikidata]

The parietal eminence (parietal tuber, parietal tuberosity) is a convex, smooth eminence on the external surface of the parietal bone of the skull. It is the site where intramembranous ossification of the parietal bone begins during embryological development. It tends to be slightly more prominent in men than in women, so may be used to help to identify the sex of a skull.^[1]
