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.
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.
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 ]
Less neotenized skull than of a majority of modern humans [7] Low, elongated skull with flat lambdoid region; Broad cranial vault with "en bombe" parietal morphology; A flat basicranium [15] [16] [17] 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)
The frontal sinuses are one of the four pairs of paranasal sinuses that are situated behind the brow ridges. Sinuses are mucosa -lined airspaces within the bones of the face and skull. Each opens into the anterior part of the corresponding middle nasal meatus of the nose through the frontonasal duct which traverses the anterior part of the ...
