Brow ridge

Categories: Anatomy, Aesthetics, Lookism

The '''brow ridge''' or '''supraorbital ridge''' is the bony protrusion of the upper eye socket. Its function is to protect the [[eyes]] and acts as a reinforcement for the eye socket itself against fracture. 

The term '''supraorbital rim''' is ambiguous as it may refer to either the outer protrusion of the supraorbital ridge, or the [[supraorbital margin]].

Males, compared to females, generally have more protrusive supraorbital rims. It's a feature of [[facial masculinity]].

The browridge is widely viewed as a [[Chad]] characteristic in the [[incelosphere]].
== Origin and sex differences ==

Among primates and apes, including humans, the brow ridge has been argued to have evolved due to mastication since the muscle which involved in mastication creates a pressure on the brow ridge bone.<ref>[https://pubmed.ncbi.nlm.nih.gov/8215263/ Role of the mandibular first molar in the development of the supraorbital region in apes and humans]</ref><ref>[https://link.springer.com/article/10.1007/BF02447216 Supraorbital ridge and masticatory apparatus I: Primates]</ref><ref>[https://www.sciencedirect.com/science/article/abs/pii/S0940960215000400 The relationship between skull morphology, masticatory muscle force and cranial skeletal deformation during biting]</ref> Men have more pronounced and square brow ridges, closer to that of great apes, while women's eyebrows are roundish and less protruding, closer to the anatomy of babies (see [[neoteny]]).
