næsebrusken

Næsebrusken, also known as the nasal septum, is a cartilaginous structure located in the middle of the nose. It divides the nasal cavity into two separate passages, one for each nostril. The nasal septum plays a crucial role in the process of breathing and smelling, as it helps to filter, warm, and humidify the air we inhale. It also contributes to the overall shape and structure of the nose.

The nasal septum is composed of several parts, including the perpendicular plate, the vomer, and the septal cartilage. The perpendicular plate is a thin, vertical bone that forms the front part of the septum, while the vomer is a bone that forms the back part. The septal cartilage is a flexible, C-shaped piece of cartilage that connects the perpendicular plate and the vomer, providing support and flexibility to the septum.

The nasal septum can sometimes deviate from its normal position, a condition known as a deviated septum. This can occur due to various reasons, such as trauma, allergies, or congenital abnormalities. A deviated septum can cause breathing difficulties, nasal congestion, and other symptoms. In such cases, medical intervention, such as septoplasty, may be required to correct the deviation and improve breathing.

In summary, the næsebrusken is a vital structure in the nasal cavity that plays a significant role in breathing and smelling. Understanding its structure and function can help in diagnosing and treating nasal-related issues.
