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.
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.
In general, the male skeleton is more robust than the female skeleton because of male's greater muscles mass. Male skeletons generally have more pronounced brow ridges, nuchal crests, and mastoid processes. Skeletal size and robustness are influenced by nutrition and activity levels.
Pronounced brow protrusion, often with ocular distension (frontal bossing) Pronounced lower jaw protrusion (prognathism) with attendant macroglossia (enlargement of the tongue) and teeth spacing; Hypertrichosis, hyperpigmentation and hyperhidrosis may occur in these people.

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.
Near the middle of the squamous part of occipital bone is the external occipital protuberance, the highest point of which is referred to as the inion.The inion is the most prominent projection of the protuberance which is located at the posterioinferior (rear lower) part of the human skull.

[12] [10] [2] An earlier quantitative genetic analysis of a Finnish population also revealed that inheritance of incisor shoveling is monogenic. [13] The 1540C allele of EDAR is also strongly correlated with the presence of shovel-shaped incisors and hair thickness, as found in a study conducted on the DNA from Japanese populations. [ 2 ]
