Which bone is commonly known as the cheekbone?

The bone commonly known as the cheekbone is the zygomatic bone. This bone forms the prominent part of the face and contributes to the orbits of the eyes. It is easily recognizable and plays a significant role in the structure of the facial skeleton; its robustness provides support for the surrounding soft tissues and facilitates facial expression. The zygomatic bone articulates with several other bones, including the maxilla, frontal, and temporal bones, contributing to the complex architecture of the skull and the protection of the underlying structures, such as the eyes.

In contrast, the maxilla is the upper jawbone, which holds the upper teeth and forms part of the eye sockets, but it is not the bone referred to as the cheekbone. The mandible is the lower jawbone, responsible for holding the lower teeth and enabling the movements necessary for chewing. The nasal bone, on the other hand, forms the bridge of the nose and has no relation to the structure of the cheeks. Understanding the specific function and position of the zygomatic bone in relation to other facial bones is key to recognizing its role in the anatomy of the face.
