This cavity is divided by the nasal septum and contains the turbinates, scroll-like bones that increase the internal surface area essential for air processing. Specialized olfactory receptor neurons located high in the nasal cavity detect these molecules and transmit signals directly to the olfactory bulb in the brain.
Understanding Turbinates, Septum, and Nostril Structure
They are far more than simple holes; they are dynamic, functional structures that warm, filter, and condition the air we breathe while playing a crucial role in our sense of smell. Airborne odorant molecules enter the nasal cavity and dissolve in the mucus lining the olfactory epithelium.
The nasal passages add moisture to prevent the delicate tissues of the lungs from drying out. The migration of these sensory organs to the front of the face in land animals allowed for the simultaneous processes of breathing and smelling.
Understanding Turbinates and the Nasal Septum Structure
Because they are exposed to the external environment, the nostrils are susceptible to a variety of conditions. The nostrils are the pair of external openings of the nasal cavity, positioned centrally on the face beneath the nose bridge.
