Question: 1 / 1775

What anatomical location does the term nasion refer to?

End of the jawbone

Root of the nose

The term "nasion" refers specifically to the anatomical landmark located at the bridge of the nose, where the nasal bones meet the frontal bone. This area is significant in both dental and medical contexts because it serves as a reference point for various measurements and procedures, particularly in orthodontics and facial surgery. Understanding the location of the nasion is essential for professionals in the dental field as it helps in the alignment of dental structures and in the analysis of facial proportions.

Other options, while they refer to identifiable anatomical locations, do not relate to the nason and thus are not applicable in this context. The end of the jawbone, center of the shoulder blade, and surface of the upper arm are distinct anatomical features that serve different purposes in the body, but they are not connected to the term nasion.
