Question

What structure is lined with ceruminous glands?
A) pharyngotympanic (auditory) tube
B) auricle (pinna)
C) external acoustic meatus (auditory canal)
D) tympanic membrane

Accepted Answer

The external acoustic meatus (auditory canal) is lined with ceruminous glands, which secrete earwax (cerumen) to protect the ear canal from dust and debris. The other structures listed (pharyngotympanic tube, auricle, and tympanic membrane) do not have ceruminous glands.
