The Superciliary Arch is a bony prominence located above the eye socket, which helps protect the eye. Synonyms for this term include brow ridge, supraorbital ridge, or brow bossing. The Superciliary Arch serves as the attachment site for various muscles of the forehead and eyebrows. Its size and prominence can vary between different individuals and species. In some cases, a pronounced Superciliary Arch can indicate a stronger and more prominent forehead. Its features have long been used in anthropology to study the evolution and development of the human skull. Regardless of its shape or size, the Superciliary Arch plays an important role in both function and appearance of the human face.
