The square or rectangular structure found in the midline of the face is called what?

The structure described as a square or rectangular structure found in the midline of the face refers to the nasal bones. These bones are located at the bridge of the nose and are small, paired bones that provide shape and support to the nasal region. The nasal bones are essentially the only bones that articulate directly with the skin and cartilage of the nose, contributing to the overall structure and aesthetics of the face.

The maxilla, while central to the facial structure and located above the upper jaw, is not characterized as a square or rectangular shape when compared to the shape of the nasal bones. The palatine bones are located further back in the oral cavity and contribute to the structure of the hard palate and part of the floor of the nasal cavity, but they are not positioned in the midline of the face in the same way. The mandible, or lower jawbone, is also a critical structure of the face but is distinctly larger and has a more curved shape, making it less relevant to the description provided in the question.

In sum, the nasal bones accurately fit the description of a square or rectangular structure found in the midline of the face, serving as a foundational component of the nasal framework.
