What is cartilago septi nasi?

Cartilago septi nasi, also known as septal cartilage or nasal septum, is a strong, flexible, and elastic cartilage that separates the two nostrils in the nose. It is located in the midline of the nose and extends from the nostril openings to the posterior border of the nasal cavity. The cartilage is shaped like a triangle, with the base attached to the bony structures of the nose and the apex pointing downwards.

The cartilago septi nasi provides support to the nose and helps maintain its shape. It also plays a crucial role in breathing and the sense of smell. The septal cartilage is covered by a layer of mucous membrane that helps to humidify and filter the air passing through the nose.

Injuries or abnormalities in the cartilago septi nasi can lead to a deviated septum, where the cartilage is displaced to one side, obstructing airflow and causing breathing difficulties. Treatment for a deviated septum may involve surgery to reposition the cartilage or remove excess tissue.
