The external nose's bony framework is composed of the nasal bones, the frontal processes of the maxillae, and the nasal part of the frontal bone. These bones form the upper one-third of the nose's structure. The lower two-thirds are made up of cartilage, including the lateral nasal cartilages, major alar cartilage, and septal cartilage. Here's a more detailed breakdown: Nasal Bones: These are two small, oblong bones that articulate with each other in the midline to form the bridge of the nose. Frontal Processes of Maxillae: These are extensions of the maxillary bones that contribute to the sides of the nose and connect with the nasal bones. Nasal Part of Frontal Bone: This forms the superior part of the nose, where it connects with the frontal bone of the skull. Cartilages: The cartilaginous part of the nose is made up of several cartilages that give the nose its shape and flexibility. The major cartilages include the lateral nasal cartilages, major alar cartilages, and septal cartilage, which form the lower two-thirds of the nose.
