The brow ridges are often not well expressed in human females, as pictured above in a female skull, and are most easily seen in profile. The brow ridge, or supraorbital ridge known as superciliary arch in medicine, is a bony ridge located above the eye sockets of all primates and some other animals.
Supraorbital ridge, a prominent, trabecular (spongy) brow ridge; 1,500–1,740 cm 3 (92–106 cu in) cranial capacity (modern human: 1425 cm 3) Lack of a protruding chin (mental protuberance; although later specimens possess a slight protuberance) Crest on the mastoid process behind the ear opening
The term also refers to the underlying bone that is slightly depressed, and joins the two brow ridges. It is a cephalometric landmark that is just superior to the nasion . [ 1 ]
It arches transversely below the superciliary arches and is the upper part of the brow ridge. It is thin and prominent in its lateral two-thirds, but rounded in its medial third. [3] Between these two parts, the supraorbital nerve, the supraorbital artery, and the supraorbital vein pass. The supraorbital nerve divides into superficial and deep ...

Cro-Magnons were anatomically similar to present-day Europeans, West Asians, and North Africans; however, they were more robust, having larger brains, broader faces, more prominent brow ridges, and bigger teeth, compared to the present-day average. The earliest Cro-Magnon specimens also exhibit some features that are reminiscent of those found ...
Middle-to-Late Pleistocene East Asian archaic human skullcaps typically share features with Neanderthals. The skullcaps from Xuchang feature prominent brow ridges like Neanderthals, though the nuchal and angular tori near the base of the skull are either reduced or absent, and the back of the skull is rounded off like in early modern humans ...
