articulation lecture 16

Question 1

oral cavity

Answer 1

• most significant
• undergoes most change
• shape changes based on tongue or mandible movement
• extends from lips to faucial pillars at back of oral cavity

Question 2

buccal cavity

Answer 2

• lateral to oral cavity
• space between posterior teeth and cheeks
• plays role in oral resonance when mandible is depressed

Question 3

positions of buccal cavity

Answer 3

laterally - cheeks
medially - teeth
posterior - third molar

Question 4

pharyngeal cavity

Answer 4

• tube 12 cm in length
• behind nasal cavities to vocal folds
• lined with muscle capable of constricting the space of tube for swallowing
• important in closing veropharyngeal port (opening between oropharynx and nasopharynx)

Question 5

oropharynx

Answer 5

• immediately posterior to fauces
• superior boundary - velum
• inferior boundary - hyoid bone

Question 6

laryngopharynx

Answer 6

• superior boundary - hyoid bone
• anterior boundary - epiglottis
• inferior boundary - esophagus

Question 7

nasopharynx

Answer 7

• space above soft palate
• anterior boundary nasal chonchae
• lateral wall is orifice of eustacian tube

Question 8

what is the most significant cavity that undergoes the most change?

Answer 8

oral cavity

Question 9

what is the shape in the oral cavity altered by?

Answer 9

movement of tongue or mandible

Question 10

the oral cavity extends from the lips to where?

Answer 10

the faucial pillars

Question 11

what is the buccal cavity lateral to?

Answer 11

oral cavity

Question 12

the buccal cavity plays role in oral resonance when what is happening?

Answer 12

the mandible is depressed

Question 13

how long is the pharyngeal cavity?

Answer 13

12 cm

Question 14

pharyngeal cavity is from where to where?

Answer 14

nasal cavities to vocal folds

Question 15

the pharyngeal cavity is lined with muscle that does what?

Answer 15

constricts the space of the tube for swallowing

Question 16

what cavity helps with closure of velopharyngeal port

Answer 16

pharyngeal cavity

Question 17

what is the superior boundary of oropharynx

Answer 17

velum

Question 18

what is the inferior boundary of oropharynx

Answer 18

hyoid bone

Question 19

what is the superior boundary of laryngopharynx

Answer 19

hyoid bone

Question 20

what is the anterior boundary of laryngopharynx

Answer 20

epiglottis

Question 21

what is the inferior boundary of laryngopharynx

Answer 21

esophagus

Question 22

what is the anterior boundary of nasopharynx

Answer 22

nasal chonchae

Question 23

what is the lateral wall of nasopharynx

Answer 23

orifice of eustacian tube

Question 24

what is the space above the soft palate?

Answer 24

nasopharynx

Question 25

what is immediately posterior to the fauces

Answer 25

oropharynx

Question 26

source filter theory of vowel production

Answer 26

- voice is generated by the vocal folds and routed through the vocal tract where it is shaped into the sounds of speech - changes in shape of tongue, mandible, soft palate, & other articulators govern resonance characteristics of the vocal tract - resonances of tract determine sound of given vowel

Question 27

how do you change the shape of your oral cavity (smaller or larger, lengthening or shortening it)

Answer 27

move tongue around

Question 28

what happens when you change the shape of the oral cavity

Answer 28

resonant frequency changes; changes the sound that comes out of the mouth

Question 29

what is the source of vowels

Answer 29

phonation

Question 30

what is the source of consonants

Answer 30

turbulence of frication or combination of voicing and turbulence

Question 31

when volume decreases, what happens to frequency

Answer 31

it increases

Question 32

what is the source-filter theory

Answer 32

- vocal folds produce a tone - the filter of that vocal tract changes that tone/frequency - changing shape of oral cavity changes resonant frequencies which changes sound that comes out of your mouth

Question 33

what is articulation

Answer 33

the process of joining two elements together

Question 34

what is the articulatory system

Answer 34

the system of mobile and immobile articulators brought into contact for the purpose of shaping the sounds of speech

Question 35

what are immobile articulators

Answer 35

alveolar ridge, hard palate, teeth

Question 36

what are mobile articulators

Answer 36

tongue, lower jaw, soft palate, cheeks, pharynx, larynx/hyoid bone

Question 37

what is the most important arcticulator

Answer 37

the tongue; super important for vowel production

Question 38

what does the lower lip achieve greater than the upper lip?

Answer 38

greater velocity and force and does most of work in lip closure

Question 39

what is lower lip attached to

Answer 39

mandible

Question 40

how are lips resistant to interference

Answer 40

they adjust and accommodate to physical restraints

Question 41

what is the lower lip capable of

Answer 41

rapidly altering its rate of closure

Question 42

what articulator is a helper that assists the lips

Answer 42

mandible

Question 43

the mandible changes position for what

Answer 43

tongue movement

Question 44

how is mandible important for mastication

Answer 44

the mandible elevates, grinds laterally and then depresses in a rhythmic fashion

Question 45

what does mandible do for speech

Answer 45

it elevates and depresses with slight modifications, quick adjustments

Question 46

tongue tip elevation

Answer 46

t, d

Question 47

tongue tip depression

Answer 47

k, g

Question 48

lateral margins relaxation of tongue

Answer 48

l

Question 49

velum

Answer 49

- closed for non-nasal speech - open for nasal sounds - opens and closes in coordination w other articulators avoiding the effect of nasal resonance on other phonemes
