Cartilago alaris major, also known as the alar cartilage, is a term used to describe a specific anatomical structure found in the human body. It is a major component of the external nose, contributing to its shape and structure. The term "cartilago" refers to cartilage, a tough, flexible connective tissue found in various parts of the body.
The cartilago alaris major is located at the lateral aspect of the nasal septum, forming the lower lateral cartilage or the lower part of the nasal wing. It is responsible for providing support and shape to the external nose, contributing to the overall appearance of the face.
This particular cartilage is characterized by its curved shape and malleability, allowing it to be easily molded and manipulated during surgical procedures such as rhinoplasty. It plays a crucial role in maintaining the structural integrity of the nose and ensuring proper airflow through the nasal passages.
Functionally, the cartilago alaris major works in conjunction with other nasal structures, such as the upper lateral cartilage and the septum, to regulate the flow of air and control the direction of airflow during breathing. It also helps to protect the nasal cavity from injury, acting as a cushion against external forces.
Overall, the cartilago alaris major is an essential component of the external nose, providing support, shape, and functionality to this prominent facial feature.
