Identify the hard and soft palate, the epiglottis and hyoid bone.



Identify the oral cavity, nasopharynx, oropharynx, vallecula and laryngopharynx.



Why is the inferior part of the laryngopharynx not seen as a space?

There are two sphenoid sinuses (right and left) that are within the body of the sphenoid bone.


 


On occasion they may extend into the wings of the sphenoid bone.

There are two sphenoid sinuses (right and left) that are within the body of the sphenoid bone.



On occasion they may extend into the wings of the sphenoid bone.



The orbits are lateral to the ethmoid sinuses while the nasal cavity is medial to them.



The inferior part of the laryngopharynx that is continuous with the esophagus is not seen as a space because it is not surrounded by cartilage

The image on the left is through the orbits and mastoid processes and is superior to the image on the right that is through the maxillary sinuses and atlas.

The images above are from two different coronal planes. Which is more anterior? What clues did you use to determine this?



#17 and 24 and nasal conchae. Which two are they?

Which air spaces are present in the two images (#1, 3, 6, 23, 29, 37)?



Notice the continuity between spaces #1 and #23. What does this represent?



What bones do #11, 16, 32 and 36 indicate?


What suture does #13 indicate?


The image on the left is through the orbits, maxillary sinuses and conchae, and is anterior to the image on the right that is through the sphenoid air sinuses, choanae and ramus of the mandible.

The image on the left is through the orbits, maxillary sinuses and conchae, and is anterior to the image on the right that is through the sphenoid air sinuses, choanae and ramus of the mandible.



The superior nasal concha is not seen in the image on the left because it is too anterior. This concha is superior to the posterior portion of the middle concha.



The superior nasal concha is also anterior to the sphenoid sinus, which is why it is not seen in the more posterior image on the right.



The continuity between spaces #1 and #23 is the foramen through which the maxillary sinus drains (called the maxillary ostium).



Note that the maxillary sinus drains into the middle meatus.
