Septal cartilage

A flexible structure that forms the framework of the nasal septum, separating the nasal cavities.

Septal cartilage is a type of hyaline cartilage located within the nasal septum, providing the necessary support and structure to this vital area of the nose. It plays a key role in maintaining the shape of the nasal passages, allowing for proper airflow and structure.

Respiratory system

Function

The primary function of septal cartilage is to support the structure of the nasal septum, which divides the nasal cavity into two nostrils. This separation is crucial for proper airflow, enabling efficient respiration. The cartilage allows the nasal septum to maintain its shape despite the forces exerted during breathing and other activities. Additionally, it contributes to the overall aesthetics of the face by shaping the nose. By maintaining the integrity of the nasal structure, septal cartilage helps to facilitate the functions of smelling, filtering, and humidifying the air we breathe.

Location

Septal cartilage is situated in the midline of the nasal cavity, specifically forming the anterior part of the nasal septum. It lies between the bony portion of the septum, which is made up of the vomer and the perpendicular plate of the ethmoid bone, and the soft tissues of the nose. The cartilage extends from the front of the nasal cavity, near the nasal tip, to the junction of the bones at the back of the nasal cavity. Its location is pivotal, as it helps to define and stabilize the overall structure of the nasal passages, allowing for effective breathing and normal functionality.

Did You Know?

The nasal septum is typically composed of both cartilage and bone, with septal cartilage forming its front portion.
Deviations in the nasal septum, often resulting from injury or congenital conditions, can impact breathing efficiency.
Hyaline cartilage, the type that makes up the septal cartilage, is known for its glossy appearance and smooth surface, aiding in airway flow.
