Anatomical Region of the Nasal Cavity Containing Nose Hairs

Question

Anatomical region of the nasal cavity containing nose hairs.
A) nasal septum
B) olfactory mucosa
C) nasal conchae
D) vestibule
E) uvula

Accepted Answer

The vestibule is the anatomical region of the nasal cavity containing nose hairs (also known as vibrissae) that trap large particles and prevent them from entering the respiratory system. The nasal septum separates the left and right sides of the nasal cavity. The olfactory mucosa is located higher up in the nasal cavity and is responsible for detecting smells. The nasal conchae are bony structures that create turbulence and increase the surface area of the nasal cavity, aiding in the warming and humidification of air. The uvula is a fleshy structure at the back of the throat that aids in the closing of the nasopharynx during swallowing.
