What structure provides support to the external nose?

• A. Maxillary bone
• B. Nasal bone
• C. Frontal bone
• D. Temporal bone

Answer: (B)

The nasal bone is specifically designed to support the structure of the external nose. This small, rectangular-shaped bone forms the bridge of the nose and plays a critical role in giving shape and contour to the nasal structure. The nasal bones articulate with each other at the midline, and they also connect with surrounding structures, providing both structural integrity and aesthetic form.

In considering other bones such as the maxillary bone, frontal bone, and temporal bone, while they contribute to the overall structure of the face and skull, they do not directly form the bridge of the nose. The maxillary bone forms the upper jaw and contributes to the sides of the nose but does not provide support to the bridge itself. The frontal bone is located at the forehead and forms the upper part of the eye sockets but is not involved in the support of the external nose. The temporal bone is situated on the sides and base of the skull and does not interact directly with the nasal structure. Thus, the nasal bone is the direct and correct answer regarding the specific support provided for the external nose.
