MEATUS

The meatus are groove-like passages between the turbinates (nasal conchae) in the nasal cavity. Of the three passages (inferior meatus, middle meatus, and superior meatus) the inferior meatus is the largest and the superior meatus is the smallest. The passages are lined with mucous membrane. Nerve endings responsible for the sense of smell are located in the nasal musosa.
