What is "dorsum nasi"?

The dorsum nasi, also known as the nasal dorsum, refers to the upper part or bridge of the nose in the human body. It is the external surface that runs from the root of the nose down to the tip. The dorsum nasi is composed of bone and cartilage, and its shape and size contribute to the overall appearance of the nose. Variations in the dorsum nasi can be observed among individuals, with some having a more prominent or pronounced nasal bridge, while others may have a flatter or less prominent one.
