Which structures are responsible for not allowing air and food to pass through the wrong structure?
- Soft palate
- Vocal chords
The opening for the nose is called. whats inside and separated by what?
- The piriform aperture
- Nasal cavities separated by nasal septum
The 3 chonchae (which ones are they?) divide the nasal cavities into 3 parts?
- Inferior, superior, middle
- Inferior meatus, middle meatus, superior meatus
The cavity for the maxillary sinus is also known as the:
The perpendicular part of the ethmoid bone forms a large part of the:
The middle and superior Concha are part of this bone and the inferior is.
This paper thin, most lateral part of the ethmoid bone that forms the medial wall of the orbit is called
Between the lamina papyrachea and the upper part of the nasal cavity are the
Ethmoid air cells
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
The frontal and maxillary sinus both open into this complex area, narrow side chamber in the nasal cavity called:
The sphenoid sinus enters the nasal cavity above and behind the ______ _____ and through what opening?
- Superior conchae
- Sphenoethmoidal recess
The ethmoid cells (sinus) have several openings into the nasal cavity below and behind
The middle conchae
The naso-lacrimal duct opens beneath
The inferior conchae
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
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
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)
