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 skull itself belonged to an elderly woman and has distinctly equatorial features: pronounced prognathism, a convex forehead, slightly forward-facing cheekbones, a wide nose, flattened nasal bones, and a broad interocular space. Khwit's skull is indeed impressive: powerful brow ridges, a large face, a wide nose, and a pronounced occiput.
Frontal bossing is the development of an unusually pronounced forehead which may also be associated with a heavier than normal brow ridge. It is caused by enlargement of the frontal bone , often in conjunction with abnormal enlargement of other facial bones , skull , mandible , and bones of the hands and feet.
A sagittal crest is a ridge of bone running lengthwise along the midline of the top of the skull (at the sagittal suture) of many mammalian and reptilian skulls, among others. The presence of this ridge of bone indicates that there are exceptionally strong jaw muscles.
Frontal sinus. Each frontal sinus is situated between the external and internal plates of the frontal bone. [1] [2] Their average measurements are as follows: height 28 mm, breadth 24 mm, depth 20 mm, creating a space of 6-7 ml. [3]
SK 847 has a relatively short and narrow face, pronounced brow ridge, thick supraorbital torus, a sharp sloping frontal bone, delicate curved cheekbones, a rounded forward projecting nasal bones, an obvious supratoral sulcus, and a moderate constriction of the cranium behind the eye socket.
hypertrophic alveolar ridges and/or gums The head tends to be longer than normal from front to back, with a bulging forehead. This is because of the premature fusion of skull bones in the affected person.
A benign metopic ridge presents itself as a slight or noticeable ridge in the metopic suture (also called frontal suture), that is running down the middle of a child's forehead. [2] The child otherwise has a mostly normally shaped forehead and head. A metopic ridge is usually a benign and isolated finding.
