The mucous membrane traps particles and pathogens, moistens incoming air, and contains cilia and goblet cells.
The external nose is composed of cartilage and bone, featuring the nasal bridge, nostrils (nares), and alae.
The functions include air filtration, humidification, temperature regulation, olfaction, and resonance.
The rich vascular network aids in warming the air that passes through the nasal cavity.
The internal nose is divided by the nasal septum, which is made of cartilage and bone.
Rhinitis is the inflammation of the nasal mucosa, often due to allergies or infections.
The conchae increase surface area for air filtration and help warm and humidify incoming air.
Nasal polyps are noncancerous growths in the nasal cavity, often associated with chronic inflammation.
The three main regions are the vestibule, respiratory region, and olfactory region.
The mucous membrane is composed of ciliated columnar epithelium and goblet cells.
