자주 묻는 질문

What are the main anatomical components of the nose?
The nose consists of the external nose (supported by nasal bones and cartilages), the nasal cavity (lined with mucosa and olfactory epithelium), the nares (nostrils), and the turbinates (conchae) that increase surface area for air conditioning.
How does the nose contribute to the respiratory system?
As the primary entry point for inhaled air, the nose filters particles using nasal hairs, warms and humidifies the air using its rich blood supply, and detects harmful irritants via sensory neurons, protecting the lower respiratory tract.
What is olfactory epithelium and where is it found in the nose?
The olfactory epithelium is a specialized sensory tissue located in the superior portion of the nasal cavity. It contains olfactory receptor neurons that detect volatile chemical odorants and transmit signals to the olfactory bulb in the brain.
