The brow ridge is a nodule or crest of bone situated on the frontal bone of the skull. It forms the separation between the forehead portion itself (the squama frontalis) and the roof of the eye sockets (the pars orbitalis). Normally, in humans, the ridges arch over each eye, offering mechanical protection.
A more prominent brow bone (bone across the centre of the forehead from around the middle of eyebrow across to the middle of the other) and a larger nose bone. [3] A heavier jaw. A high facial width-to-height ratio. [4] However some studies dispute this, and testosterone reduces cheekbone prominence in males. [5] A more prominent chin.
Female skulls and head bones differ in size and shape from the male skull, with the male mandible generally wider, larger, and squarer than the female. [13] [23] In addition, males generally have a more prominent brow, an orbital with rounded border, and more greatly projecting mastoid processes. [13]
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 ]
The supraorbital foramen is a small groove at superior and medial margin of the orbit in the frontal bone. It is part of the frontal bone of the skull. [2] 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]
