Pharynx and Nose: Review Questions
1. All of the following statements about the nasopharynx are true EXCEPT:
It communicates with the nasal cavity via choanae.
The auditory tube opens along the lateral wall.
The inferior border is the epiglottis.
Pharyngeal recesses are found in the lateral walls.
The levator veli palatini muscle forms a fold on the lateral wall.
2. Concerning the lateral nasal wall:
The frontal sinus drains inferior to the middle nasal concha
The ethmoidal bulla is inferior to the inferior nasal concha.
The maxillary sinus drains superior to the middle nasal concha.
The middle meatus is superior to the middle nasal concha
The sphenoethmoidal recess is directly posterior to the inferior nasal concha.
3. When examining the nasal cavity of a patient by spreading the nostril with a speculum, you can confirm that:
The opening of the nasolacrimal duct is in the atrium
The opening of the anterior ethmoidal air cells is in the sphenoethmoidal recess
The opening of the maxillary sinus is in the inferior meatus
The frontonasal duct drains into the semilunar hiatus
The choanae are between the vestibule and the atrium
4. The ethmoidal air cells:
Are normally filled with fluid
Drain poorly because their duct exits the superior aspect of the air cells
Are fully formed at the time of birth
Are separated from the orbit by a thick plate of bone
Are lined by mucous membrane that is innervated by branches of the nasociliary nerve
5. Which of the following statements about the muscles of the soft palate is FALSE?
The palatopharyngeus muscle underlies the palatopharyngeal fold
The salpingopharyngeus muscle is part of the longitudinal muscle layer of the pharynx
The levator veli palatini is the only muscle of the palate that is innervated by CN V
The musculus uvulae is located at the boundary between the oral pharynx and the nasal pharynx
The palatoglossus muscle is innervated by the vagus nerve
6. Which of the following structures does not drain into the region inferior
to the middle nasal concha?
Maxillary sinus.
Anterior ethmoidal air cells
Middle ethmoidal air cells
Frontal sinus.
Sphenoid sinus.
