The root (the area between the eyebrows) The external openings of the nose, nostrils, are bounded laterally by the flared alae. The nasal and the frontal nose are superior, the maxillary bones are lateral, the flexible plates of hyaline cartilage are inferior. Noses vary in size and shape because of differences in nasal cartilages. Skin covering the noses anterior and lateral aspects is thin and contains many sebaceous glands.
