Nose anatomy, illustration. At left, the side view of the skull shows the nasal bones (green) and the soft tissues of the nose (blue) that includes cartilage and skin and connective tissues. At right, the frontal view is split between the skull and an external view of the face. The cartilage is seen as a thin piece of tissue (the nasal septum) dividing the nostrils, with most of the nose consisting of a space called the nasal cavity.
