Anatomy of the Nose: What to Know

The External Nose

The external nose is the part of the nose that is visible on the face. It is made up of skin, bone, and cartilage. The skin of the nose is thin and delicate, and it contains many small blood vessels. The bones of the nose are the nasal bones, which form the bridge of the nose, and the maxillae, which form the sides of the nose. The cartilage of the nose is called the septal cartilage, and it divides the nose into two nostrils.

The Internal Nose

The internal nose is the part of the nose that is located inside the skull. It is made up of the nasal cavity, the turbinates, and the sinuses. The nasal cavity is a large space that is lined with mucous membranes. The turbinates are thin, scroll-like structures that project from the sides of the nasal cavity. They help to warm and humidify the air that we breathe. The sinuses are air-filled spaces that are located around the nasal cavity. They help to lighten the skull and give our voices resonance.
