Flashcards in Lecture 22 Deck (18):
1

Describe the Oral Cavity

It is an opening in the mouoth exctending from the oral opening fo the mouth to the anterior faucial pillars

2

Describe the pharyngeal cavity

tube extending from just behind the nasal cavities superiorly to the esophagus and epiglottis inferiorly

3

Describe the buccal cavity

lateral to the oral cabity the space between teh teeth and the cheeks

bounded by the cheeks laterally, teeth medially and lips anteriorly

4

Describe the nasal cavity 

bounded by the cribiform plate of the ethmoid and the sphenoid bone superiorly, the hard palate inferiorly, the nares anteriorly and the nasopharynx posteriorly

5

What are the four cacvities of the vocal tract?

oral cavity

buccal cavity

nasal cavities

pharyngeal cavity

6

What are the important landmarks/parts of the oral and buccal cavities?

 

hard palate

rugae

velum

uvula

anterior faucial pillar

posterior faucial pillar

palatine tonsils

7

Where would you touch to make someone gag?

anterior faucial pillar

8

What are the important parts/landmarks of the nasal cavities? 

 

superior nasal conchae

middle nasal conchae

inferior nasal conchae

9

What are the important parts/landmarks of the pharyngeal cavity?

 

torus tubarius (orifice of the eustacian tube)

pharyngeal tonsil

velo-pharyngeal port

10

What are the functions of the teeth?

mastication 

speech production

11

How many teeth are on each part of the mouth and what bones are they found in? 

16 upper teeth in the maxillae

16 lower teeth in the mandible 

12

What are the types of teeth and how many of each are there? 

central incisor-4

lateral incisor- 4

cuspid - 4

bicuspid- 8 (2 sets)

molar- 12 (3 sets) 

13

What is a class I occlusion?

 

upper teeth align with lower teeth; first mandibular molar is 1/2 a tothe advancedof the first maxillary molar

14

What is a class II occulsion?

first mandibular molar is retracted by at least one tooth

results in buckteeth

15

What is a class III occlusion? 

the first mandibular molar is advanced by one or more tooth of the maxillary molar 

Resulting in "prognathic jaw"

16

What are the landmarks of the lips? 

philtrum

columella

vermillion zone

cupid's bow

angle
