What makes the structure of the nose?
The shape of the nose arises from a cartilaginous framework in its lower two thirds and a bony upper portion. The outer cartilages are paired and called the upper and lower lateral (alar) cartilages.
Within the nose, a midline wall called the nasal septum separates the nasal cavity. This is also made of cartilage in its anterior portion and bone in its posterior part..
