Question

Which of the following is not lined with a ciliated mucous membrane?
A)Vestibule
B)Posterior nares
C)Trachea
D)Primary bronchi

Accepted Answer

The vestibule is the space between the nostrils and the nasal septum and is lined with skin, not a ciliated mucous membrane. The posterior nares (also called the choanae) are the openings at the back of the nasal cavity and are lined with a ciliated mucous membrane, as are the trachea and primary bronchi.
