SUPRAORBITAL RIDGE Meaning and
Definition
-
The supraorbital ridge, also known as the brow ridge or brow bone, refers to the prominent bony ridge situated above the eye sockets. Located in the frontal bone of the skull, this structure extends horizontally across the upper part of the eye sockets and acts as a natural frame for the eyes. Spanning from one temporal region to the other, the supraorbital ridge is typically more pronounced in certain individuals, such as males or people of certain ethnicities.
The primary function of the supraorbital ridge is to protect the underlying eye sockets and the delicate structures within them. It serves as a barrier against potential physical impacts and shields the eyes from injury. Furthermore, this bony ridge also plays a role in supporting and providing attachment to the muscles of the forehead and the upper eyelids. These muscles contribute to facial expressions, including frowning and raising the eyebrows.
From an evolutionary perspective, the supraorbital ridge can be traced back to our early ancestors, particularly Homo erectus and Neanderthals. In these species, the brow ridge was much more pronounced, likely serving as additional protection for the eyes during confrontations or hunting activities. However, as modern humans evolved, the supraorbital ridge became less pronounced, resulting in the more subtle feature we observe in contemporary human populations.
