Anterior nares
Anterior Nares
The Anterior Nares, also known as the nostrils or external nares, are the external openings of the nasal cavity. They are the primary entry and exit points for respiration in humans and many other animals.
Structure[edit | edit source]
The Anterior Nares are located on the lower part of the nose, and are separated by the nasal septum. Each nostril is surrounded by the alar cartilage, which provides structure and shape to the nose. The size and shape of the Anterior Nares can vary greatly among individuals and between different ethnic groups.
Function[edit | edit source]
The primary function of the Anterior Nares is to filter, warm, and humidify the air before it enters the lungs. The nostrils also play a key role in the sense of smell and are involved in certain facial expressions.
Clinical significance[edit | edit source]
Conditions that can affect the Anterior Nares include nasal polyps, deviated septum, and rhinitis. These conditions can lead to symptoms such as nasal congestion, difficulty breathing, and loss of smell.
