Which bone is often referred to as the "keystone" of the face?

• A. Maxilla
• B. Zygomatic Bone
• C. Mandible
• D. Nasal Bone

Answer: (A)

The maxilla is referred to as the "keystone" of the face because it is centrally located and connects with numerous other facial bones. It forms the upper jaw and plays a crucial role in the structure of the face, contributing to the formation of the mouth, nasal cavity, and the orbits for the eyes. The maxilla supports the teeth and is pivotal in functions such as chewing and speaking. Its connections to other facial bones contribute to the overall stability and integrity of the facial skeleton, making it essential for both aesthetics and function. This anatomical significance is what earns it the title of "keystone," as its structure holds together and supports the configuration of surrounding bones.
