Q
Nose and nasal cavity; slide 1:
- What’re the external/internal nostrils called?
- What’re the names of the two paired cartilages and where are they?
- Where’s the septal cartilage?
- What’s the purpose of the cartilage?
A
-
5
Q
Nose and nasal cavity; slide 2:
- What’s the septal cartilage made of?
- Where are the internal nares?
- What two bones form the roof of the nasal cavity
- What forms the floor of the nasal cavity?
- What special structures do you have on turbinates/conchae?
A
-
6
Q
Nose and nasal cavity; slide 3:
- On the _____ walls, there are three _____-covered projections: the s____, m_____ and i______ turbinates (conchae)
- What do these structures do?
- They assist to what?
- What can be triggered and activate what?
A
-
7
Q
Paranasal sinuses:
- A ring of _____ (cavities) surround the nose - the f____, s_____, e_____ and m_____ sinuses.
- What do sinuses do?
- What do sinuses allow?
- Where does sinus mucus drain into?
- What does infected mucus do and lead to?
A
- Sinus mucus drains into the pharynx. Infected mucus can block the drainage, creating a partial vacuum within the sinuses, as the air is absorbed leading to a “sinus headache”
8
Q
Pharynx:

A
-
9
Q
Nasopharynx
- Anterior/Posterior to nasal cavity?
- Extends from where to where?
- During swallowing, the ____ ___ and ____ swing back and up covering it thus preventing what?

- Infected pharyngeal tonsils can enlarge and what? = ____ voice
A
-
10
Q
Oropharynx
- Posterior to the ____ cavity and extending from the ____ ___ to the _____
- Epithelium changes in this region - a s___, s____ e____, to protect the throat from what?
- Contains what two tonsils? And which one of these are commonly infected in children?
A
-
11
Q
