Question

What region contains the coarse nasal hairs?
A)Pharyngeal
B)Vestibular
C)Olfactory
D)Laryngeal

Accepted Answer

The vestibular region of the nasal cavity contains coarse nasal hairs, also known as vibrissae, which act as a barrier to trap large particles and prevent them from entering the respiratory system. The olfactory region contains specialized cells for detecting smells, while the pharyngeal and laryngeal regions are part of the throat and voice box, respectively, and do not contain nasal hairs.
