SUPRAORBITAL ARCH Meaning and
Definition
-
The supraorbital arch, also known as the brow ridge or brow bossing, is a prominent bony structure located just above the eye sockets on the forehead. It is formed by the frontal bone, which is part of the skull.
The supraorbital arch typically displays as a gently curved ridge extending horizontally across the forehead, parallel to the eyebrow line. It can vary in size and shape among individuals and is more pronounced in some ethnic groups. In general, males tend to have more prominent supraorbital arches than females.
The main function of the supraorbital arch is to provide support and protection for the eyes. It helps to maintain the shape of the eye sockets and provides a structural barrier against potential impact or injury. Additionally, the supraorbital arch plays a role in maintaining the positioning and stability of the surrounding facial bones.
From an evolutionary perspective, the supraorbital arch is believed to have served as a protective feature, especially in early human ancestors. It may have helped shield the eyes and forehead from physical trauma or direct sunlight. However, in modern humans, the supraorbital arch is primarily an anatomical characteristic that varies in size and prominence, contributing to facial diversity among different populations.
