Which bones form the structure of the cheeks?

The structure of the cheeks is primarily formed by the zygomatic arches, which are better known as the cheekbones. These paired bones contribute significantly to the facial skeleton, providing support and shape to the face. They also help form the lateral walls of the orbits, where the eyes are located.

The zygomatic bones articulate with several other bones in the skull, including the maxilla, the temporal bone, and the sphenoid bone, creating a prominent position in the facial anatomy. Their location and structure contribute not only to the facial contour but also to the protection of the underlying structures, such as the maxillary sinuses.

In contrast, while the maxillary bones contribute to the upper jaw and help form the foundation of the face, they do not specifically define the cheek structure. The nasal bones are part of the bridge of the nose and do not contribute to the cheek formation. Lastly, the palatine bones are located at the back of the oral cavity and play a role in forming the hard palate but are not involved in the cheek structure. Therefore, zygomatic arches are the bones that distinctly form the cheeks.
