ZYGOMATIC ARCH Meaning and
Definition
-
The zygomatic arch is a prominent bony structure found in the facial skeleton of mammals, including humans. Also known as the cheekbone, it is formed by the union of two bones: the zygomatic process of the temporal bone and the temporal process of the zygomatic bone. This arch serves as an important anatomical landmark, forming a portion of the lateral wall of the orbit (eye socket) and contributing to the shape and contour of the face.
The zygomatic arch plays a crucial role in protecting and supporting the soft tissues of the face. It provides attachment sites for several muscles involved in chewing and facial expressions, including the masseter and the temporalis muscle. As a result, it has a significant impact on the functional and aesthetic aspects of the face.
In addition to its structural significance, the zygomatic arch also serves as a diagnostic feature in forensic anthropology and archaeology. Its size, shape, and orientation can be used to determine the sex, age, and ancestry of skeletal remains, aiding in the process of identification.
Overall, the zygomatic arch is an important anatomical feature that contributes to the facial structure, stability, and functionality of mammals, including humans.

Etymology of ZYGOMATIC ARCH
The word "zygomatic arch" comes from the Greek roots "zygoma" meaning "yoke" or "bar" and "archos" meaning "chief" or "ruler". In anatomy, the zygomatic arch refers to the bony structure formed by the zygomatic bone (cheekbone) and the temporal bone of the skull. The term was first coined in the mid-17th century, combining these Greek roots to describe this prominent bony arch.
