  1. Air from the nasal cavity and passage for food in the oral cavity both pass through the ___________ and they separate at the ____________. Where do each lead to?
    • Oropharynx
    • Hypopharynx 
    • Food passes backwards to the esophagus and air forward into the Larynx and the Trachea.
  2. Which structures are responsible for not allowing air and food to pass through the wrong structure?
    • Soft palate
    • Epiglotis
    • Vocal chords
  3. The opening for the nose is called. whats inside and separated by what?
    • The piriform aperture
    • Nasal cavities separated by nasal septum
  4. The 3 chonchae (which ones are they?) divide the nasal cavities into 3 parts?
    • Inferior, superior, middle
    • Inferior meatus, middle meatus, superior meatus
  5. The cavity for the maxillary sinus is also known as the:
    Maxillary antrum
  6. The perpendicular part of the ethmoid bone forms a large part of the:
    nasal septum
  7. The middle and superior Concha are part of this bone and the inferior is.
    • Ethmoid bone
    • Its own bone
  8. This paper thin, most lateral part of the ethmoid bone that forms the medial wall of the orbit is called
    lamina Papyrachea
  9. Between the lamina papyrachea and the upper part of the nasal cavity are the
    Ethmoid air cells
  10. The frontal sinus opens into the nasal cavity by way of a narrow passage that exits above the ulcinate process called:
    The fronto-nasal duct
  11. The frontal and maxillary sinus both open into this complex area, narrow side chamber in the nasal cavity called:
  12. The sphenoid sinus enters the nasal cavity above and behind the ______ _____ and through what opening?
    • Superior conchae
    • Sphenoethmoidal recess
  13. The ethmoid cells (sinus) have several openings into the nasal cavity below and behind
    The middle conchae
  14. The naso-lacrimal duct opens beneath
    The inferior conchae
  15. The inner end of the short tunnel for blood vessels and nerves to the nose and palate is, and where does it open
    • Sphenopalatine foramen
    • in back of the superior meatus
  16. This muscle inserts on the petrous temporal bone and comes downward and medially to join with its other half forming a sling, it lifts upward and backward the soft palate.
    Levator veli palatini
  17. This muscle arises from the above the medial pterygoid plate and hooks around the hamulus and insertes in the palatal aponeurosis. It tightens the palate during swallowing (also helps open the auditory tube)
    Tensor palati
  18. What is the function of the auditory tube?
    Keep the pressure stable within the inner and outer ear
  19. Piece of skin and cartilage between the nostrils.
  20. The nasal cavity is separated from maxillary sinus by this flake of bone:
    Uncinate process
