What is the primary function of the zygoma in the human skull?

The primary function of the zygoma, commonly referred to as the cheekbone, is to contribute to the formation of the eye socket. This bone helps create the lateral wall and floor of the orbit, which houses the eye and its associated structures. The zygoma plays a crucial role in providing structural integrity and shape to the face while also protecting the ocular contents. This function is essential for both aesthetics and the proper alignment and positioning of the eye within the skull.

In contrast, while the zygoma does have some connection to other bones in the skull, including the maxilla (upper jaw) and the temporal bone, its primary role is specifically linked to the eye socket. Thus, choices related to the support of the jaw, structure of the forehead, or connections to the temporal bone do not encapsulate the main function of the zygoma.
