What is the term for the anterior ridge of the nose composed of the root, bridge, and protruding lobe?

The term for the anterior ridge of the nose that includes the root, bridge, and protruding lobe is known as the dorsum. The dorsum is the part of the nose that extends from the root, which connects the nose to the forehead, down to the tip, or apex, of the nose. This anatomical structure plays a significant role in the overall appearance and shape of the nose, contributing to its definition and aesthetic profile.

The nasal bridge describes only the bony part of the nose and does not encompass the entire anterior ridge, while the tip of the nose refers specifically to its most distal point. The columella is the tissue that separates the nostrils and is part of the nasal base, rather than the anterior ridge itself. Thus, the dorsum is the most comprehensive term for the anterior features of the nose.
